WORKING GUNS IN PAIRS AND INTERVALS BETWEEN GUNS.
The necessity of using guns in pairs for mutual support in case of mechanical trouble no longer holds good. Guns in the open have usually been placed not less than 50 yards apart. This enables the best use to be made of the ground as protection against artillery fire and for concealment. In trench warfare guns should usually be placed singly, arrangements being made for “cross fire” and mutual support between the guns of any particular section of the defensive line.
