(Still in Chapter 2: Killing)

He talks of seeing 'Crispy Critters' all over the hill. (We had that nape stuff too, man was it ever a game changer.)

Psychologically I had become identified with the threatened [and surrounded US recce team] and the advancing enemy was no longer human. I didn't kill people, sons, brothers, fathers. I killed 'Crispy Critters.' It could have been krauts, nips, huns, boche, gooks, infidels, towel heads, imperialist pigs, yankee pigs, male chauvinist pigs... the list is as varied as human experience. This dissociation of one's enemy from humanity is a kind of pseudospeciation. You make a false species out of the other human and therefore make it easier to kill him.
Richard Holmes in 'Acts of War' also covers this (pg 365-75) and has more to say on the matter. In addition he reminds readers that soldiers tend to create and unofficial name for everything. So if every item of equipment is given a new name does it really come as any surprise that this also happens to the enemy?
