Collective Field Practices on Landscape Targets.
No. 1.
Object: To teach concentration of fire.
Directions: Fire is opened on a given point on the landscape as ordered. If the point is clearly indicated and recognized, and if sighting and fire are accurate, a dense group of shot-holes will be made on sky-screen, the point of mean impact being a point the correct height vertically above the point of aim [see Appendix, VI, para. 5 (i)].
No. 2.
Object: To teach distribution of fire.
Directions: Fire is opened along a given line of country as ordered. The shot-holes should appear evenly distributed along a line on the sky-screen at a certain height, and immediately above the line of country indicated [see Appendix, VI, para. 5 (ii)].
No. 3.
Object: To teach the use of combined sights.
Directions: As in No. 1, but half the firers will adjust sights 50 yards above and half 50 yards below the range given. Results will show two groups, which would be merged into one group of great depth in the case of fire of sufficient volume, such as that of two platoons, and illustrates the use of combined sights for increasing the zone of effective fire.
