Arrangements should be made so that guns so placed may be able to fire to their front, should an emergency make this desirable.
This can be done by:—
Arranging that some sandbags can be removed and the gun fired to the front through the loophole thus made.
In this connection it must be remembered that:—
(a) If the sandbags are left in place for a considerable time without being removed, they may become embedded and be found unmovable. (b) That loopholes filled with single sacks will not be bullet-proof.
Training the gunners to:—
(a) Remove the gun quickly from the tripod and fire from the top of parapet without it. (b) Lift the gun and tripod out of the trench and fire it from some previously selected spot.
Note.—Both these methods require much practice.
Every endeavour should be made to conceal the position of the gun from the front.
Gun emplacements must therefore be made to appear exactly like the remainder of the trench or breastwork.
