The patrol had been halted just before the photo was taken because a fallen tree was blocking the trail. Not wanting to take any unnecessary chances, Lt. Blakely called for 3.5 inch rockets (better known as the bazooka) to fire a round into the tree to check for booby traps. I took this photo while we were waiting for the rocket team to make its way to the front of the column.
Two rocket rounds were fired into the tree. Each round produced a secondary explosion meaning that there had been two booby traps in the fallen tree. Good call, Lt. Blakely.
