Soldiers are trained to kill the enemy, but in reality, the impact of this can be formidable. When Lieut. Col. (Ret.) Bruce Black made his first drone strike, he stepped outside the box and threw up. In basic training recruits are trained to fire on command at human cut-outs, but can a person really be prepared to take a life and, if so, how does one not have remorse? Veterans share their stories.
