But if they're there they kinda have to do it. Numerous studies have concluded that men in combat are usually motivated to fight not by ideology or hate or fear, but by group pressures and processes involving (1) regard for their comrades, (2) respect for their leaders, (3) concern for their own reputation with both, and (4) an urge to contribute to the success of the group. Repeatedly we see combat veterans describe the powerful bonds that men forge in combat as stronger than those of husband and wife. This bonding is so intense that it is fear of failing these comrades that preoccupies most combatants. Countless sociological and psychological studies, the personal narratives of numerous veterans, and the interviews I have conducted clearly indicate the strength of the soldier's concern for failing his buddies. The guilt and trauma associated with failing to fully support men w h o are bonded with friendship and camaraderie on this magnitude is profoundly intense. Yet every soldier and every leader feels this guilt to one degree or another. For those who know that they have not fired while their friends died around them, the guilt is traumatic.
