Note 351 — Chapter VI · Positional Warfare
Reading edition
Prior to the raid various combinations of flamethrower fuels and pressure were extensively used. The purpose was to determine the maximum effective range of the flamethrower teams in order to “neutralize the hand-grenade throwing potential of the enemy, this being one of the major problems confronting assault elements on other raids.” Final tests resulted in flame being thrown more than 40 yards up hill. 1/5 ComdD, Mar 53, App. IVf, p. 3.
