Note 317 — THE FORMAL TACTICS OF INFANTRY. (continued 6)

The Belgian Drill Regulations (1907) give the following details in regard to the fire effect of a French four gun battery: In “progressive fire” (tir progressif), 32 rounds cover a space 100 m. wide and 400 m. deep (1 fragment covers 6 sq. m.). When direct laying is employed, one fragment covers 2 sq. m. In “progressive fire with sweeping” (tir progressif avec fauchage), 48 shrapnel cover a space 200 m. wide and 400 m. deep, each fragment covering 8 sq. m. Depending upon the range, 11⁄2 to 5 minutes are required to secure adjustment. (See p. 119 supra).
