Advance in line of section, in single or double file keeping as closed up as possible with 30 yards intervals between sections.
The second line should be 250 to 300 yards behind the first.
128.—Case 2. Shrapnel shells bursting high.
Much less dangerous than when bursting at right height as initial speed of bullets is spent. Same formation as for Case 1.
129.—Case 3. Burst area of Time-fuse high explosive shells bursting at right height.
The area of burst is opposite to that of shrapnel: short depth, large width, only 7 to 10 yards depths as opposed to 60 to 100 yards in width.
130.—Protective Formation against Time-fuse high explosives.
Advance in line of section, single or double file, keeping as closed up as possible with 60 to 100 yards intervals between sections.
The second line may be 15 yards behind the first.
