in selecting positions, observing fire, and correcting errors, the maximum of accuracy should be attained. If the enemy is entrenched against frontal fire, good results may be expected from accurate distance fire, owing to the angle of descent of the bullet causing the low parapet or shallow trench to be no protection.

It will rarely be advisable for machine guns to follow infantry into the firing line, where they
