Lesson 9. – CLEANING
A INSTRUCTOR’S NOTES
Aim
1. To teach the method of cleaning the gun and tripod.
Class and instructors
2. Squads under squad instructors. Squads seated in a semi-circle around the gun.
Periods
3. One 45-minute period. This lesson may well be taught in the first period allotted to cleaning stores.
Stores
4. Gun, tripod, spare parts box and case, condenser can and tube, cleaning rod, flannelette and cleaning material.
Preparation
5. Gun and tripod mounted, with the rest of the kit laid out on a table.
B CONDUCT OF LESSON
Approach
6. Tell the squad the aim of the less (see para 1).
7. For the gun to function satisfactorily under all conditions, its maintenance is of the first importance. The degree of cleaning carried out depends on the employment of the gun. In barracks, when the guns are probably not in daily use, the amount of cleaning need not be more than an occasional oiling. On active service, however, conditions will decide how often the gun is cleaned.
Cleaning
8. When guns are not continually in use, cleaning will consist of wiping over the outside of the gun and tripod, and all parts of the mechanism that can be reached without stripping, with an oily rag, and the inside of the barrel oiled. If the gun has been fired and then returned to store, the barrel will need cleaning daily for several days. For this the cleaning rod or double pullthrough can be used.
9. Explain, with the squad practising, that the gun will be stripped, and a piece of flannelette (4 X 2) placed in the eye of the cleaning rod and the rod pushed through the barrel several times. The muzzle protector will always be on the barrel when it is cleaned. This process will be repeated with fresh pieces of flannelette until the bore is cleaned. Then a piece of flannelette (4 X 1½) will be oiled and pushed through the barrel.
10. If the barrel cannot be cleaned with flannelette alone, the double pullthrough and gauze will be used. Before using the pullthrough, examine it to see the weight is not bent, the cord is in good condition, the gauze is oiled and the muzzle protector is on the barrel.
Thread the pullthrough through the barrel from the breech end, and with one man holding the barrel behind his back and underneath his armpits, and with one man on either end of the pullthrough, it will be pulled backwards and forwards through the barrel, the cord being kept taut to prevent wear on the breech. After using the double pullthrough, the barrel is cleaned with the cleaning rod and flannelette and re-oiled.
11. Another method of cleaning the barrel is with boiling water. The procedure is the same as for the rifle. Ensure the squad know this method.
12. Practice the squad using the double pullthrough.
13. Periodically the gun should be completely stripped down, and all parts left clean and dry for inspection. If on inspection any part of the gun and tripod is found to be rusted, the rust will be removed by using flannelette soaked in paraffin. After cleaning off the rust all traces of paraffin must be removed and the parts well oiled. After inspection all parts should be oiled and reassembled.
14. Spare parts and remaining gun stores should also be examined and checked for damage, cleanliness and deficiencies.
Conclusion
15. Questions to and from the squad.
16. Sum up main points.
Lesson 10. – EXAMINATIONS, TESTS AND ADJUSTMENTS (1)
A INSTRUCTOR’S NOTES
Aim
1. To teach the soldier how to examine and test parts of the gun to see that they are in working order and if necessary to carry out certain adjustments.
Class and instructors
2. Squads under squad instructors. squad seated in semi-circle around the gun.
3. One 45-minute period.
Stores
4. Gun, tripod, spare parts box and case.
Preparation
5. Gun and tripod mounted with the rest of the stores laid out on a table.
B CONDUCT OF LESSON
Approach
6. Tell the squad the aim of the lesson (see para 1).
Examinations and tests
7. Describe the points to look for in examining and testing the following parts:-
(a) Muzzle attachment.- Should be free from fouling or burrs, the disc clean, and the split pin and chain in good condition. The blast deflector should be fitted correctly.
(b) Muzzle cup.- Should be clean and the threads neither damaged nor worn.
(c) Steam tube.- The keeper screw should be in its correct position and the sliding valve working. This can be tested by rocking the gun.
(d) Foresight.- The blade should be in good condition.
(e) Front cover catch.- Should be in working order.
(f) Fusee spring and fusee.- These should be in good condition. The vice pin should not be bent.
(g) Tangent sight.- The apertures should be undamaged, the top and bottom screws secure and the slide moving freely.
(h) Rear cover catch.- Test the automatic fastening of the rear cover when closed and that the rear cover lock screwed axis pin is tight.
(j) Safety catch.- Test the automatic action of the spring.
Weighing and adjusting the fusee spring
8. Explain and demonstrate the method of weighing the fusee spring. The lock should be removed and the loop of the spring balance placed over the know of the crank handle. The balance should then be pulled vertically upwards. The reading indicated when the crank handle begins to move will be the weight or tension of the fusee spring. The mean of three readings should be taken and the weight should be between seven and nine pounds.
9. If the spring is over or under weight, the weight can be adjusted by the vice pin. Generally, six clicks or three complete revolutions of the vice pin makes a difference of about one pound. Turning the vice pin upwards decreases the weight and downwards increases the weight.
10. State that the tension of the fusee spring should always be kept as high as possible during firing, consistent with maintaining a rate of fire about 500 rounds per minute.
11. Practice the squad in weighing and adjusting the fusee spring.
Conclusion
12. Questions from the class.
13. Questions to the class on examinations and tests, and further practice if necessary in weighing the fusee spring.
14. Sum up main points and progress made.
Lesson 11. – EXAMINATIONS, TESTS AND ADJUSTMENTS (2)
A INSTRUCTOR’S NOTES
Class and instructors
1. Squads under squad instructors. Squads seated in a semi-circle around the gun.
Periods
2. One 45-minute period.
Stores
3. Gun, tripod, spare parts case, drill cartridges, wall diagrams and a pointer.
Preparation
4. Gun mounted with the remaining stores laid on a table.
B CONDUCT OF LESSON
Approach
5. Repeat aim of Lesson 10. This lesson deals with another series of examinations and tests.
Examinations and tests
6. Describe the method of examining and testing the following parts:-
(a) Firing lever.- Ensure that the thumb-piece cannot be pressed unless the safety catch is raised.
Ensure that when the safety catch is raised and the thumb-piece pressed the lock is fired.
(b) Trigger bar and spring.- Inspect for burrs or roughness on the trigger bar. Make sure that the spring forces the trigger bar forward quickly.
(c) Connecting rod.- See that the adjusting nut is tight.
Testing the recoiling parts
7. Describe and demonstrate the method of testing the recoiling portions. This is done by removing the fusee spring, putting the crank handle vertical and working the recoiling portions backwards and forwards. They should move freely.
8. State that the recoiling portions must be weighed periodically. Explain and demonstrate how this is done. The fusee spring is removed and the crank-handle raised until it is vertical. The loop of the spring balance is placed over the right end of the crank shaft and pulled slowly to the rear. Immediately the recoiling portions begin to move, the weight shown on the spring balance is read. The mean of three readings should be taken and should not exceed four pounds.
9. Practice squad.
Testing the lock
10. State that there are five tests for the lock, each designed to test a different portion. The lock should pass each test, before being subjected to the next one. Explain and demonstrate these tests using the gun and wall diagrams:-
(a) Side and extractor levers.- The feedblock should be removed and the front cover left raised. The crank handle is drawn back on to the roller and then released. With the finger and thumb, the extractor is now tested for vertical play. If the extractor can be moved vertically, it indicates that the side or extractor levers are worn.
(b) Bents of sear and firing pin.- With the feedblock removed and the front cover raised, the crank handle is drawn back on the roller. Keeping the thumbpiece pressed, the crank handle is allowed to go slowly forward onto the check lever. If the extractor jumps upwards as the firing pin goes forward, it indicates that the bents of the sear and firing pin are worn, and the striker is hitting the wall of the firing pin hole in the rear of the extractor.
(c) Extractor.- The face of the extractor should be examined for burrs or flaws. If there is any doubt, a good drill cartridge should be slid along the extractor grooves.
(d) Nose of the trigger and bent of the tumbler.- The lock is cocked and the sear depressed. The firing pin should now be held back by the nose of the trigger engaging in the bent of the tumbler, If it is not, then these are worn.
(e) Firing pin.- First, see that the point of the firing pin is not broken. A breakage in the body of the firing pin can be recognised without stripping the lock. The lock spring is released with the extractor raised. If undamaged the firing pin will then protrude from the firing pin hole. If it does not protrude, or if it does protrude and is not withdrawn when the lock is re-cocked, some part of the firing pin is broken.
11. Practice the squad in the lock tests.
Weighing the lock spring
12. Tell the squad that the lock must be weighed periodically to test the tension of the lock spring. Describe and demonstrate the procedure for doing this. The lock should be removed. With the crank handle held on the roller, the lock is then re-inserted in the gun but not connected on to the connecting rod. The connecting rod is then allowed to fold and go under the crankshaft, and the crank handle allowed to go forward. The lock is now held firmly in the gun with the side levers head free to move.
The loop of the spring balance is placed over the side levers head and drawn slowly upwards. Directly the tail of the tumbler moves, the reading is taken. The mean of three readings should be assessed and should be between 12 and 14 pounds.
13. Practice the squad in weighing the lock.
Conclusion
14. Questions from the squad.
15. Further practice as time allows in the tests. Soldiers should be required to explain their tests through practice.
16. Sum up main points.
Lesson 12. – EXAMINATIONS, TESTS AND ADJUSTMENTS (3)
A INSTRUCTOR’S NOTES
Aim
1. To teach the soldier further examinations and tests.
2. To teach the soldier to examine and pack the barrel.
Class and instructors
3. Squads under squad instructors. Squads seated in a semi-circle around the gun.
Periods
4. One 45-minute period.
Stores
5. Gun, tripod, spare parts box and case, asbestos packing and as many spare barrels as are available.
Preparation
6. Gun and tripod mounted. The other stores should be laid out on a table.
B CONDUCT OF LESSON
Approach
7. State the aim of the lesson (see para 1) and emphasize that a high degree of skill in packing the barrel is required. The efficient functioning of the gun depends to a large extent on good packing.
Examining the barrel
8. Tell the squad that the barrel should be examined for rust, cuts, erosion, bulges or metallic fouling. Explain that erosion is the pitting of the barrel caused by the force of explosion and is most liable to occur at the breech end of the barrel.
9. Describe and demonstrate the best method of examining the barrel. The barrel should be removed from the gun. Holding the barrel, first close to the eye and then some distance from the eye, the bore should be examined. The examiner should look at the walls of the barrel and not look through. The barrel should be rotated slowly to make sure that no portion is missed. The lead should be carefully examined to ensure no undue erosion has taken place. The barrel should now be reversed and examined carefully from the muzzle end in a similar manner. Point out that metallic fouling may cause inaccuracy in shooting.
Packing the breech end of the barrel
10. State that if the gun leaks at the breech end, the packing is at fault and it must be removed and renewed. The barrel casing must first be emptied and the recoiling portions removed.
11. Explain and demonstrate the method of packing the breech end of the barrel. A strand of asbestos is wound in the cannelure of the barrel and pressed together with a thin piece of wood or the point of a screwdriver until the cannelure is full. The asbestos is then smoothed down flush with the barrel. Before replacing the barrel in the gun, the packing is soaked in oil; this will swell the packing and give a tighter fit and also reduce friction.
12. Practice the squad.
Packing the muzzle end of the barrel
13. Explain and demonstrate how to pack the muzzle end of the barrel. The muzzle attachment is removed and the packing gland unscrewed. A length of asbestos is then oiled and wound loosely round the barrel, and as it is wound it is pushed in with a piece of wood or a screwdriver, until it is just behind the front cap of the barrel casing. The gland is then screwed on hand tight. The lock is hung and the recoiling portions worked by hand to ensure they move freely. If the packing is too tight, the gland can be removed and one or two strands of asbestos taken out. Finally the packing gland is screwed home using the combination tool.
14. Practice the squad.
Testing the packing
15. State that the packing should be tested by putting into the barrel casing sufficient water to cover the barrel, and working the recoiling portions backwards and forwards. There should be no leakage.
Finally the recoiling portions should be tested for correct weight.
Testing and examining miscellaneous parts
16. Show the squad the points to look for when examining the feedblock. The slide should be working freely and the pawls and springs in good condition.
17. Point out the parts of the sliding shutter that require attention. The catch and spring should work automatically and the shutter should move freely. If the shutter is difficult to move, it should be examined for:-
(a) Dirt or grit.
(b) Dented bottom plate, due to the connecting rod being dropped when there is no lock in the gun.
18. State that axis and all other pins should be inspected for serviceability.
Examining and adjusting the tripod
19. Tell the squad that there are many places where slight play may occur. Although the play in each part may be slight, the accumulated effect may cause serious unsteadiness in the gun. This can usually be seen in DP tripods.
There are two types of play:-
(a) Vertical play.- This is usually found in the elevating gear. Demonstrate show this is taken up by loosening the jamming bolt, screwing in the tumbler nut and retightening the jamming bolt. After making the adjustment, test to see is the play has been taken up.
(b) Lateral play.- This is normally due to the jaws of the crosshead opening up, and it is the armourer’s job to adjust.
20. Practice the squad in adjusting the elevating gear.
21. Point out the following further points for examination:-
(a) Clutch plates free from grit.
(b) Jamming handles not bent.
(c) Chains correct.
(d) Feathers on joint pins.
Conclusion
22. Questions to the squad.
23. Questions to squad on examining the feedblock, sliding shutter and tripod.
24. Further practice if necessary in packing the barrel.
25. Sum up main points and progress made.

A INSTRUCTOR’S NOTES
Aim
1. To teach the method of preparing the gun for firing.
2. To teach the special measures required before using the gun in very cold weather, in sandy conditions or before landing operations.
Class and instructors
3. Squads under squad instructors. Squads seated around the guns in a semi-circle.
Periods
4. One 45-minute period. This can well be a period immediately before firing the guns on the range.
Stores
5. Gun, tripod, spare parts case and box, cleaning rod, condenser can and tube, flannelette and cleaning material.
Preparation
6. Gun and tripod mounted with the other stores ready to hand.
B CONDUCT OF LESSON
Approach
7. Tell the squad the aim of the lesson (see paras 1 and 2).
Method of conducting
8. In the first part of the lesson no new technique is taught. The instructor should detail the sequence of preparing the gun and the squad should do all the preparation with the instructor supervising.
Preparing the gun for firing
9. Have the gun stripped down and all parts cleaned and examined by the squad.
10. See that the following parts are now oiled:-
Outside of barrel.
Recoiling portions including the face of the lock.
Ramps.
Trigger bar.
11. Detail one of the squad to check the oil in the traversing handles and in the can in the spare parts case.
12. Have the gun reassembled and order the following parts to be dried:-
Inside of the barrel.
Muzzle cup.
Muzzle attachment.
Blast deflector.
13. See that the muzzle cup and front cone are screwed tight. Unless these are secure they may work loose during firing and cause an accident.
14. Have the gun levelled and the barrel casing filled with water. See that the condenser tube is undamaged and test the fitting of it to the gun. Order a man to fill the condenser can two-thirds full of water.
15. Detail men of the squad to weigh:-
Fusee spring.
Recoiling portions.
Lock spring.
16. Have the contents of the spare parts box and case checked.
17. Order the squad to pack the cannelure of the spare barrel and to examine the tripod.
18. All sealed liners must be inspected for corrosion of the soldering. Any liners corroded should not be used.
19. Finally, state that the barrel should now be gauged with the .306-inch gauge plug. (See Lesson 16).
Action in cold weather
20. State that the following action will be taken to prepare the gun in cold weather:-
(a) lubrication, including packings, will be carried out with the following oils:-
Above 40 degrees F, Oil OX-52 or OX-13.
Zero degrees to 40 degrees F, Oil OX-13 or Grease LG-380.
Zero degrees to -40 degrees F, 50/50 mixture of kerosene, vapourising, and Oil OX-13, or Grease LG-380. (In emergency, kerosene burning may be used in lieu of kerosene vapourising).
At temperatures of 40 degrees F and below, particular attention will be paid to the following points:-
(i) Mechanism will be stripped, wiped clean and lubricated with oils as above.
(ii) Ensure that firing pins are free in their housings, as the firing pins may freeze up, although other parts of the mechanism work freely.
(iii) Elevating gears will be thoroughly rinsed with gasoline, allowed to dry and then lubricated with oils as above.
(b) The weight of the recoiling portions will be kept as low as possible, ie, between 2 lb and 3lb and the fusee spring will be adjusted to not more than 7 lb at the start of firing. The recoiling portions will be worked by hand at frequent intervals.
(c) Straw, sacking or blankets should be wrapped around the barrel casing. When hard frosts are expected barrel casings will be emptied and refilled with water diluted with 30 per cent glycerine, glycerine residue or glycol.
When it is necessary for the solution to be “topped up” water only will be added when glycerine or glycerine residue has been used, as these do not boil away; this is not the case with glycol.
Care will be taken not to exceed the 30 per cent solution glycol as a stronger solution gives off harmful fumes.
In temperatures from zero to -40 degrees F a solution of 50 per cent glycerine or glycerine residue will be used. Glycol will not be used in these temperatures.
Action in sandy countries
21. State that only a small quantity of oil will be used. Working parts will be wiped over with a slightly oily rag, which will prevent rust through the night and will give sufficient lubrication for working the gun during firing.
Action before landing operations
22. State that all equipments which are to be involved in landing operations will be smeared with Grease LG-380 or in an emergency Grease LG-280 thinly applied. Equipment which will be needed for immediate use will be smeared on the outside only. The internal working parts will be lubricated as in para 20 (a) above. The earliest opportunity will be taken of wiping dry and re-oiling.
Conclusion
23. Sum up the main points.
24. Sum up main points.
Lesson 14. – POINTS DURING FIRING
A INSTRUCTOR’S NOTES
Aim
1. To teach the soldier the points to which attention should be paid during firing to ensure that the gun will maintain a high rate of sustained fire.
2. To explain the action to be taken if defective ammunition is encountered.
Class and instructors
3. Squads under squad instructors. Squads seated in a semi-circle around the stores.
Periods
4. This lesson may be taught either before or during a period of range work. Alternatively it can, if necessary, be taught with Lesson 13.
Stores
5. Gun, condenser can and tube, tripod, spare parts box and case and ammunition liners (one with unbroken label).
B CONDUCT OF LESSON
Approach
6. Tell the squad the aims of the lesson. (See paras 1 and 2).
Points during fire
7. State that the supply of water must always be kept in mind. As soon as the water begins to boil and as long as it continues to boil, about 1½ pints will be lost for every two belts fired.
8. Explain that the No. 2 must ensure that:-
(a) The belt is in line with the feedblock.
(b) The belt has free movement.
(c) The cardboard packing strips are not removed from the belt before firing.
Unless these points are attended to, stoppages will result.
9. State that all repairs must be carried out immediately. To replace any part of the lock, the ordinary sequence for stripping the lock is followed until the broken part is reached. The only exemption to this is in the case of a broken lock spring when the parts fall clear. In such a case, a new lock spring may be inserted without stripping the lock.
10. Point out that the following duties should be carried out during a lull in firing:–
(a) The bearing parts of the barrel, the recoiling portions, the ramps and the trigger bar should be oiled.
(b) The tightness of the front cone, muzzle cup and jamming handles should be checked.
(c) It should be made sure that the end of the condenser tube is below the level of the water in the condenser can.
11. Practice the squad as necessary.
Defective ammunition
12. State that should ammunition be found defective in any way, the following procedure will be adopted:–
(a) The type of ammunition,the manufacturer’s initials and the date of manufacture will be carefully recorded.
Point out where these details can be found on the label.
(b) The liner will be returned to the unit quartermaster and any other ammunition of this type will be set aside and not used.
Conclusion
13. Questions to and from the squad.
14. Sum up main points.
Lesson 15. – POINTS AFTER FIRING
A INSTRUCTOR’S NOTES

1. To teach the soldier the points that must be carried out after firing.
Class and instructors
2. Squads under squad instructors. Squads seated in a semi-circle round the stores.
Periods
3. This lesson can be taught immediately after firing on the range.
Stores
4. Gun, tripod, condenser tube and can, spare parts case and box, cleaning rod, flannelette and cleaning material.
B CONDUCT OF LESSON
Approach
5. State the aim of the lesson.
6. The instructor can best teach this lesson by telling the squad what points require to be carried out stage by stage and by supervising their work.
7. Tell the squad that there are certain points which must be carried out immediately after firing on the range and other points which must be dealt with later, on return to barracks.
On the range
8. The following points must be carried out on the range:–
(a) The gun is unloaded and the lock, blast deflector, muzzle attachment and muzzle cup removed ,and the front cone loosened.
(b) Superficial fouling is removed from the barrel with the cleaning rod and oiled flannelette, followed by dry flannelette. The barrel is then re-oiled.
(c) The lock, blast deflector, muzzle attachment and cup are oiled.
(d) Finally, the gun is re-assembled. It may be of assistance in cleaning the barrel on return to barracks if the warm water is left in the barrel casing.
On return to barracks
9. The following points must be carried out on return to barracks:–
(a) The gun is stripped and all parts thoroughly cleaned.
(b) The tension of the fusee spring is reduced.
(c) If necessary, the barrel can be cleaned with boiling water as in Lesson 9, para 11.
(d) In order to prevent the formation of rust due to condensation of moisture on the outside of the barrel, the barrel casing should be emptied and the screws and cork plugs removed to allow a free circulation of air through the casing.
If the gun is likely to be unused for any length of time, the packing should be removed from the cannelure and front packing gland.
(e) The tripod and spare parts should be overhauled and cleaned.
Conclusion
10. Questions from the class.
11. Inspect the gun and equipment.
12. Sum up main points and discuss any faults.
Lesson 16. – BARREL LIFE
A INSTRUCTOR’S NOTES
Aim
1. To teach how to determine the probable remaining life of a barrel.
2. To show how to compile MMG history sheets.
Class and instructors
3. This should only be taught to officers and NCOs. Squads should be of not more than eight officers or NCOs. The squad should be seated in a semi-circle around the gun.
Periods
4. This period will take approximately 20 minutes.
Stores
5. Gun and tripod, cleaning rod, flannelette, as many gauges and spare barrels as available and MMG history sheets.
B CONDUCT OF LESSON
Approach
6. Tell the squad the aims of the lesson. The knowledge of the probable life of a barrel is of assistance to a MG unit commander in estimating the number of barrels required for a prolonged shoot.
Gauge plug
7. Describe the .306-inch gauge plug. These are the principal features to which attention should be called:–
(a) The plug is accurately dimensioned to .306-inch for about 1½ inches from one end.
(b) The flat surface is graduated in 1/10 inches from 2.75 inches to 4.5 inches from one end.
8. State that the following instructions will be adhered to when using the gauge plug:–
(a) Before gauging, barrels should be cleaned.
(b) Do NOT gauge when the barrel is warm, ie after using boiling water, or when the friction of the double pullthrough has warmed the barrel.
(c) Inspect the gauge periodically to ensure that it has not burred or worn.
(d) When the plug is not in use it must always be kept slightly oiled in the case provided for it.
(e) Check the gauge periodically with the gauge held by the unit armourer.
9. Explain and demonstrate the method of using the plug:–
(a) When the barrel is not in the gun.– The case is unscrewed and the plug is removed. The two portions of the case are screwed together again and the threaded end of the plug is screwed into the shorter end of the case, so that the plug and case now form a straight rod. Without using force, the plug is inserted as far as it will go into the breech of the barrel and the measurement in inches is read on the graduated stem of the gauge. The reading should be taken from the rear end of the barrel face where the rim of the cartridge seats itself.
(b) When the barrel is in the gun.– The process is the same as in (a) above, but the threaded end of the plug is screwed into the longer portion of the case so that the instrument is L-shaped. The rear cover is opened, the lock removed and holding the plug with the handle uppermost as when using a clearing plug, it is gently inserted into the barrel.
Stress that under no circumstances whatever are marks or scratches to be made on the barrel.
10. Practice the squad in using the plug with various barrels in and out of the gun.
11. Describe the method of determining the probable remaining barrel life using the table given below. State that the table is only to be used as a general indication of what may be expected:–
| Plug enters in inches | Probable remaining life in rounds |
| 2.75 | 7,000 |
| 2.80 | 6,000 |
| 2.85 | 5,000 |
| 2.90 | 4,000 |
| 2.95 | 3,200 |
| 3.00 | 2,600 |
| 3.05 | 2,150 |
| 3.10 | 1,750 |
| 3.15 | 1,420 |
| 3.20 | 1,100 |
| 3.25 | 800 |
| 3.30 | 600 |
| 3.35 | 400 |
| 3.40 | 250 |
| 3.45 | 100 |
| 3.50 | REJECT |
12. Emphasize most strongly that barrels must be rejected for shoots in which safety is involved when the gauge enters at 3.5 inches, irrespective of the number of rounds actually fired.
MMG history sheets
13. State that the MMG history sheet provides an accurate and easily compiled method of recording:–
(a) The number of rounds fired by each barrel.
(b) The entry of the gauge plug.
(c) Any casualties sustained by the gun.
It is the responsibility of the No. 1 under the supervision of the section commander to maintain the history sheet for his gun and enter it up at the end of each period when live ammunition is used.
14. Explain that one sheet is used for each gun and describe briefly how to enter it up.
15. A suggested pro forma is shown on the next page.
Conclusion
16. Questions to and from the squad.
17. Sum up main points.
