Letter tanks and flamethrower tanks from the 1st Tank Battalion had periodically traveled a road out in No Man’s Land in front of Hill White and had received incoming mortar rounds en route to designated raids and firing positions. Cpl. Jerry Ravino recalls that the enemy walked mortars up this road while the Marines transferred flame tanks to be stationed at COP2 for 30-day periods. Direct 105mm rounds were fired at designated targets from the turret on top of COP2. Reports of such activity were supplied by Recon Company patrols, air observations, and the commanding captain at COP2.
