Fire should only be opened in the first instance by the order of the senior officer present, and in all cases should be reserved as long as possible.
The battery of machine guns may also be used during the cavalry combat as already described in the last chapter, and when used as a reserve on a flank, should take up "positions of observation" if the ground permits, from which they can repulse a flank attack, while remaining ready to move off at a moment's notice to any point where they may be required.
