Several emplacements should be made for each gun, and practice should be made in moving guns quickly from one emplacement to another.
Guns may be placed—In the Front Line of Trenches.—This may be taken as the general rule.
In Support Trenches.—There are occasions when it may be advisable to place guns in the support trenches.
Here they may be arranged so as to:—
Prevent a further advance of the enemy should they capture the front line.
Enfilade the front line should it be captured.
Sweep the communication trenches.
In Positions in Rear.—If the ground is favourable it may be possible to place guns, in concealed positions, in rear of the entrenched line.
They can be arranged so as to:—
Fire over the trenches and sweep the ground in front.
