It is unlikely that observation will be obtained with larger bursts.
Rapid Fire.
In groups of from 30 to 50 rounds, the firer pausing slightly between each group to confirm the alignment of sights.
Traversing Fire.
Distributed laterally, and applied in a series of small groups, the object being to cover as wide a front as possible, with a minimum of volume. (Groups should consist of from 5 to 10 rounds only.) A belt of 250 rounds should cover a frontage of 25 yards in one minute.
Swinging Traverse.
For trench warfare, and against dense targets at close ranges, the traversing clamp being kept fairly loose and the gun traversed evenly and smoothly from side to side, both hands retaining their hold on the traversing handles.
Combined Sights.
When two or more guns are working together, the depth of the effective zone can be increased by ordering different elevations for each gun, both, however, using the same point of aim.
The respective depth and width of effective zones may be taken as being:—
