But when the sections have been hastily collected together and placed under the B.M.G.O., without time for making the above arrangements, the result has usually been that sections have been dispersed without definite orders or a complete understanding of the situation, and effect has been lost.
In trench warfare the successful co-operation of the machine guns assisting in the defence of any particular section of the entrenched line has been obtained by:—
1. A previous reconnaissance of the whole line by the B.M.G.O.
2. Diagrams made of own and enemy’s trenches.
3. The number of emplacements.
This has enabled rapid concentration of the requisite number of guns only on any one portion of the enemy’s line, and has prevented unnecessary opening of fire and the consequent waste of ammunition.
In many cases, however, Officers in command of troops in sections of trench line have considered they are also in command of the machine guns placed in that portion of the trench occupied by their troops. This has led to:—
1. The disadvantage of dual control.
2. The guns being placed in the same emplacement day after day.
3. The arrangements of Machine Gun Officer being interfered with.
