1951: Chapter 10 – Gun Drill

INTRODUCTORY NOTES

Aim

1. To teach the soldier his duties in handling the weapon as a member of a gun team.

Instructors notes

2. During gun drill, the gun will be mounted in the sitting position, but the instructor must emphasize that on active service and during the later stages of training, the tripod will always be adjusted to suit the ground and cover available.

3. All orders are shown the thick type throughout this part of the pamphlet.

4. When the instructor wishes to explain, demonstrate or criticize, he will first order “Rest” to allow the gun number to relax. On this order, the No. 1 will knock down the tangent sight. Before the drill is resumed he will esnure that the gun numbers adopt the correct position and are alert and ready for any order. This will be done by ordering “Position” when, if the sight had previously been knocked down, the No. 1 will raise them.

5. The instructor must insist on a high standard of drill throughout and see that the gun numbers remain still and in their correct position on the completion of any movement.

6. Although all lessons of gun drill are written for coming into action from the carrier, if carriers are not available it will be possible to bring the guns into action from the ground. The stores should be laid out on the ground as follows:

The tripod on the left, with the legs to the rear, and the dial sight close to it.

The gun, with the muzzle forward, condenser tube attached and spare parts case placed two paces to the right of the tripod.

Two liners, the condenser can and the aiming post two paces to the right of the gun, with the condenser can on the right.

The position of the gun numbers and the words of command will be given as for the carrier.

On the command “Mount” the gun numbers will kneel by their respective stores. Nos. 1 and 2 will put on the dial sight and spare parts case, with the strap over the right shoulder and the case hanging on the left side.

7. Whenever possible in gun drill as many guns as are available should be used to give maximum squad practice.

Safety precautions

8. On all occasions when the gun and drill cartridges are used for instructional purposes, the instructor will carry out the following safety precautions.

(a) Inspect all locks to ensure that the striker does not protrude through the firing pin hole.

(b) Inspect all ammunition to ensure that all cartridges are drill.

9. When service stores are used, (a) above does not apply.

Approach

18. Tell the squad that you are now going to teach them the technique of mounting and dismounting the tripod.

Mounting the tripod

19. Demonstrate slowly and explain that the No. 1 stands astride the tripod, loosens the jamming handles simultaneously and grasps the crosshead as far forward as possible with both hands, the thumbs being down the front of the crosshead. He will then swing the tripod upwards and forward to open the two front legs, and with the three legs resting on the ground, he will raise the socket until it is upright. To assist this, and to ensure the mounting is upright, the No. 1 should assume a half sitting position with the elbows supported on the inside of the thighs, and keeping the socket steady with his left hand, he will tighten both jamming handles with his right hand. A final pressure will now be exerted on the jamming handles, and the No. 1 will sit down behind the tripod and remove the crosshead and elevating joint pins with the left and right hands respectively, and hold them.

Dismounting the tripod

20. Demonstrate slowly and explain that the No. 1 will replace the two pins and turn the handles down to prevent them falling out, jump to his feet and stand astride the tripod. He will loosen both jamming handles simultaneously, allowing the tripod to collapse on the ground.

Standing on the left of the tripod he will grasp the crosshead with both hands, and with a sharp forward and upward movement allow the two front legs to fold under, at the same time taking a pace forward and placing the tripod on the ground. He will then sink down on to his right knee and tighten both jamming handles.

Aim

1. To teach the soldier to develop a consistent tap so that the line of sight is displaced 15 minutes each time the gun is tapped.

Class and Instructors

2. Squads under squad instructors, assembled in single rank on one flank of the stores.

Periods

3. One 45-minute period.

Stores

4. Gun carrier complete with drill stores and MG target. (Small Arms Training, Vol V, 1945, Fig 38).

Preparation

5. Stores loaded on the carrier, and if wet, groundsheets should be placed on the gun positions.

B CONDUCT OF LESSON

Preliminaries

6. Safety precautions.

Approach

7. Detail a gun team, order “Fall In,” “Mount” and “Dismounted Action.” When the gun is in action order the team to fall out.

8. Give the aim of the lesson (see para 1), and state that the methods of engaging all types of machine gun targets depend on the fact that the No. 1 can bring bursts of fire down 15 minutes of angle apart. It is therefore essential that every man can tap his gun consistently through 15 minutes.

Consistency of tap

9. Tell the squad that the first stage is to develop a consistent tap with both hands. Place the dial sight on the gun and then demonstrate a consistent tap with both hands.

10. Practice the squad until all of them can tap consistently. The instructor must not move onto the next stag until he is satisfied that they can do so.

11. The instructor should bring out the following points:-

(a) When tapping with either hand the gun must be held correctly with the other hand and the safety catch kept raised.

(b) The eyes must be directed to the front to observe fire.

Adjusting the clamp

12. Place out the MG target 25 yards from the gun. State that the next stage is to adjust the clamp so that the tap consistently displaces the line of sight 15 minutes. Point out that the distance between the bulls on the target is equivalent to 15 minutes.

13. Demonstrate that the clamp is tightened as much as possible by the No. 1 behind the gun. By trial and error, he adjusts his tap until he discovers the stength of tap required to displace the line of sight from one bull to the next. The strength of tap should be ascertained for each hand.

14. Practise the squad. When each man has found the strength of tap required, the sintructor should impress on him that he must get the feel of that tap and remember it.

15. Tell the squad that the No. 1 can test his clamp in the field by measuring off with hand angles two points which are one degree apart. By laying on one point and tapping four taps towards the other, he should reach the second point if the clamp is correctly adjusted.

16. Practise the squad.

Tapping test

17. A method of testing the squad for correct tapping is given below:-

(a) The instructor will give the No. 1:-

(i) A suitable range.

(ii) An indication to a bull in the horizontal row.

(iii) The direction in which he is to tap.

(iv) The order to “Lay”

(b) The instructor will explain to the No. 1 that, on the order “Fire” he will fire a burst, release the thumbpiece, tap the gun and fire again. He will continue this procedure until “Stop” is ordered. The No. 1 will be told that, for this lesson only, he will not check his aim on the order “Stop” nor relay between bursts.

(c) The instructor will order “Fire” and, after a suitable number of taps, “Stop.” He will then check the aim and discuss the No. 1’s tapping.

Conclusion

18. Questions from the squad.

19. Further practice for backward men.

20. Sum up main points.

LESSON 54 – TRAVERSING AND SWINGING TRAVERSE

A INSTRUCTOR’S NOTES

Aim

1. To teach the soldier to combine consistent tapping with corrections for elevation.

2. To teach the soldier how to fire a swinging traverse.

Class and instructors

3. Squads under squad instructors, assembled in single rank on one flank of the stores.

Periods

4. One 45-minute period.

Stores

5. Gun carrier, complete with drill stores and MG target. (Small Arms Training, Vol V, 1945, Fig 38).

Preparation

6. Stores loaded on the carrier. If wet, groundsheets should be placed on the gun positions.

B CONDUCT OF LESSON

Preliminaries

7. Safety precautions.

Revision

8. Detail a gun team, order “Fall In,” “Mount,” and “Dismounted Action.” Practise the squad in Lesson 53.

Approach

9. Give the aims of the lesson (see paras 1 and 2 above).

Traversing

10. State that the No. 1 will on occasion have to engage a target that is oblique as opposed to horizontal.

11. Detail a No. 1 and get him to lay on the centre bull of the oblique row of bulls. Warn him that on the order “Fire,” he will carry on exactly as taught in the last lesson , but that this time he will re-lay the gun on to the bull immediately above or below the point to which the tap has carried it, after each tap.

12. Practice the squad in tapping and re-laying for elevation. Get the squad to criticize the consistency of tap of each No. 1.

Swinging traverse

13. Explain that this method of traversing is only employed against targets at close ranges when the normal method of traversing is likely to be too slow.

14. Demonstrate that the clamp is loosened slightly. The gun is laid on one end of the target and, when the thumbpiece is pressed, it is swung slowly to the right or left. To do this with control, the upper part of the body is left rigid and the gun swung by the weigh of the body rather than by moving the forearms.

15. The technique of firing a swinging traverse cannot be well attained without using live ammunition as the recoil helps in moving the gun. The squad should therefore be practised in firing a swinging traverse on the range when the opportunity arises.

Conclusion

16. Questions from the squad.

LESSON 55 – APPLICATION OF DIRECT FIRE ORDERS

A INSTRUCTOR’S NOTES

Aim

1. To teach the soldier how to act on the various parts of a direct fire order.

Class and instructors

2. Squads under squad instructors. The squad should be in single rank behind and between the two guns.

Periods

3. Two 45-minute periods. Lesson 68 must have been taught before this lesson.

Stores

4. Two gun carriers complete with drill stores, portable blackboard, chalk and landscape or natural targets.

Preparations

5. The instructor should select targets of various types and decide on ranges before the lesson begins. The guns should be mounted 6 – 8 yards apart facing the arc. If wet, groundsheets should be placed on the gun positions.

B CONDUCT OF LESSON

Preliminaries

6. Safety precautions.

7. Detail two gun teams, order “Fall In,” “Mount,” and “Dismounted Action.” Organize the arc of fire and order the gun teams to fall out.

8. Give the aim of the lesson (see para 1).

Approach

9. Using the blackboard, show the sequences of a direct fire order:-

(a) Designation.

(b) Range (including wind allowance if necessary).

(c) Indication of the target.

(d) Method of fire.

(e) Lay.

(f) Side wind allowance.

(g) Rate of fire.

(h) Order to fire.

Types of targets

10. With the blackboard, explain the various types of static MG targets:-

(a) Point target. A target that appears to the naked eye to have no appreciable width.

(b) Traversing target. A target that appears to the naked eye to have width. The difference in range to each end must not exceed 50 yards.

(c) Depth target. A target with a difference in range to each end of more than 50 yards. It may or may not have width.

11. Indicate one or two targets and question the squad as to what type they are.

Point targets

12. Detail a No. 1 and 2 for each gun and order “Fall In” and “Take Post.” Divide the rest of the squad into two groups, one behind each gun.

13. State that a Point target is always engaged with right and left two taps to make sure that the target is hit. Explain how the No. 1 applies “Right and left two taps.” (see Lesson 96).

14. Explain that the side wind allowance is ordered in taps up to one degree. If the allowance is of one degree or more, it is given in degrees.

15. Give a fire order onto a Point target, explaining the duties of No. 1 at each stage of the order:-

Order. Action of No. 1
(a) Designation. Becomes fully alert to receive the fire order.
(b) Range. Raises the tangent sight and sets the slide.
(c) Indication. Follows the indication and locates the target.
(d) Right and left two taps, Lay. This order indicates to the No. 1 that he must engage the target with right and left two taps. The No. 1 grasps the traversing handles correctly, raises the safety catch and reports “On”.
(e) Wind right (or left) … … … … … taps. Taps the number of taps ordered and looking through the sights, picks up the new point of aim. Reports “On.”
orWind right (or left) … … … … … degrees. With the aid of handangles picks up the new point of aim, relays and reports “On.”
(f) Rate of fire. (i) If “Rapid” is ordered, he then prepares to fire rapid.

(ii) If none is mentioned, he then knows that normal fire is required.

(g) “Fire.” Presses the thumbpiece. Taps right and left two taps, checking his aim whenever he has tapped onto the point of aim.

16. State that the No. 2 must at all times be prepared to take over as No. 1. He must therefore know the range on the gun, the target and wind allowance.

17. Practise the squad in engaging Point targets. After each target is engaged, get the rest of the squad to criticize the action of No. 1 and No. 2.

Traversing targets

18. Explain the method of engaging a traversing target. (see Lesson 99).

19. State that on the order “Traversing Lay,” the No. 1 will lay on the centre of the taregt, raise the safety catch and report “On.” Emphasize that when firing, the line of sight is re-aligned after each tap.

20. Practise the squad in engaging traversing targets.

Depth targets

21. Explain the method of engaging a depth target. (see Lesson 100).

22. Tell the squad that the method of fire will be either “Halfway up, right and left two taps, Lay,” or “Traversing Lay,” depending on whether the target has width or not. On either order, the No. 1 will lay half way up the target, raise the safety catch and report “On.” When firing, if “Halfway up, right and left two taps Lay,” has been ordered, the No. 1 will maintain his point of aim halfway up throughout. It “Traversing Lay,” is ordered, the No. 1 will realign his point of aim onto the target after each tap.

23. Practise the squad in engaging depth targets of both types.

Conclusion

24. Questions to and from the squad.

25. Ample practice will be required to ensure that the squad can respond accurately and repaidly to fire orders.

B CONDUCT OF LESSON

Approach

7. Give the aim of the lesson (see para 1 above).

Emergency action

8. Detail a gun team, order “Fall In” and “Mount” and explain that whenever the carrier is on the move, each gun number is responsible for watching a certain arc. No. 1 will watch the front and Nos. 2 and 3 their own flanks and the rear. If any member of the gun team sees a target within his arc, he will report “Target front” “Target left,” “Target right,” or “Target rear,” the direction being in relation to the carrier itself.

9. State that when a target is reported, the No. 1 will order “Stop”

10. Tell the gun team to carry out the following actions as they are detailed:-

The No. 2 will release the emergency mounting, lower the travelling stay and pass the gun to the number who is best placed to engage the target. The firer will then take the gun, load and fire. When the target has been engaged, he will unload and order “Drive on” The No. 2 will then connect the gun to the travelling stay.

11. Emphasize the following points:-

(a) The gun will not be loaded while travelling. If the belt has been partly used, it will be passed through the feedblock to assist in quick loading.

(b) The gun number who sees the target must be prepared to indicate it to the firer.

(c) Personnel not firing will keep below the armour, but will be prepared to help in maintaining the gun in action.

(d) When the gun is on the emergency mounting, the traversing clamp must always be loose.

12. Practise the squad in engaging targets, first with the carrier moving slowly and then with the carrier at speed.

Carrier signals

LESSON 60 – TESTS OF ELEMENTARY TRAINING

A INSTRUCTOR’S NOTES

Aim

1. The follwoing tests have been devised to assist officers in testing the efficiency of their men in elementary training. It is important that these tests should not be considered solely as competitions against time, for although speed if necessary, accuracy is the first essential. No man should therefore be passed as efficient unless all the points are correctly carried out, even though he may complete them in the standard time. Men who, whilst passing the tests for accuracy slightly eceed the standard time, should be tested again before being put back for further instruction.

Notes for testing officers

2. The tests will be carried out in strict accordance with the detailed instructions given under the appropriate lessons, for unless the smallest details are insisted upon, the time limit will not be applicable. In carrying out tests time can be saved if the first detachment complete Tests 1 to 4 consecutively; the remainder can be carried out as convenient.

3. It should be noted in Tests 1, 2, 3 and 4 that numbers are being tested in their particular duties as No. 1 or No. 2, and the tests should not be regarded as a test of the No. 1 only. Therefore, a man is not considered to have passed these tests until he has passed in the duties of both numbers.

4. It is essential for each man to have passed all tests before proceeding with the machine gun course.

5. The conditions of the test will be carefully explained before the test begins, including the time allowed, and when the time allowance begins and finishes. A timekeeper will be appointed. A stop watch should be used in availble.

Stores required:-

As laid down in the appropriate lessons. DP guns must be used for Tests 9, 10 and 11. In no circumstances will service guns be used.
