My brigade in Vietnam (11th LIB, Americal Division) was responsible for the My Lai Massacre. Our official nickname for the 11th Brigade was Jungle Warriors. But after My Lai we were given the unofficial designation, The Baby Killer Brigade.
Some actually seemed to take an perverse sense of pride in the label.
Most of us abhorred it though.
As stated in my initial response, it is what's inside the individual that counts.
As for My Lai, merely a breakdown of discipline within the chain of command during a time that discipline was needed the most.
United States service personnel do not as a policy deliberately seek to harm civilians. That it does happen is merely a testament to the confusion that occurs on the battlefield.
What happened at My Lai was a testament to the stupidity and derilection of duty on the parts of Cpt Ernest Medina and Lt William Calley.
Both failed to enforce discipline with their ranks when such discipline was sorely needed.
My Lai need not have happened, and the disreputable acts of a few rouge soldiers should not be a blanket condemnation of the armed forces.
War does not breed violence among returning vets.
Character defiencies with the individual in question do.
Most vets return to lead peaceful, law abiding lives.
