Now also the official death toll of American GI`s in Iraq has reached well over 1500. Of the 1500 its said that a good 1200 in killed in a direct line of fire, the rest in more normative casualties such as car accidents, suicides, self inflicted gun-shots, and a number of deaths by FRAGGING (fragging/fragmentation) , which is GI slang for:
assassination of an officer by his own troops, usually by means of a grenade.

In other words: a discontent GI drops a grenade in the officer-mass.
An estimated 5% of the officers killed in Iraq and Vietnam died by fragging.
