I was on the original "HEADHUNTERS" team in nam....we didn't get that name for nothing.... To receive "credit" for a kill , you had to produce 1 of 3 items....documents...weapons...or "parts". This was the problem, if all that was left was ..say a left ear... my CO wouldn't count that as a kill. So a dufflebag full of heads got his attention..and our unit name. We were THE scariest unit to the enemy. We had heads on pole surrounding our hooch area. The smell was....pungent to say the least. We fought on the enemies level...and lower(more). Won't send photos...but my knives were my weapons of choice. Tools of the trade , weapons of war , sinse the beginning of time , knive are our most primitive tool.
