https://en.wikipedia.org/wiki/Fragging
Fragging is the deliberate or attempted killing of a soldier, usually a superior, by a fellow soldier. U.S. military personnel coined the word during the Vietnam War, when such killings were most often committed or attempted with a fragmentation grenade, to make it appear that the killing was accidental or during combat with the enemy. The term fragging now encompasses any deliberate killing of military colleagues.
