The No Mercy Man (also known as Bad Man, Trained to Kill, and Trained to Kill USA) is a 1973 action film with elements of a modern-day Western starring Steve Sandor, Rockne Tarkington, Sid Haig, Ron Thompson, Mike Lane, and Richard X. Slattery.

After robbing a liquor store Prophet and a friend evade the local Sheriff and stop at the ranch of Mark Hand, a decorated war veteran.

Prophet and his friend make their escape with Mark puzzled that Olie doesn't want to hunt the criminals, preferring to let the sheriff handle the matter.

Despite the supporting presence of his comrades in arms and loving family Olie grows more withdrawn and prone to flashbacks to the war where he nearly kills one of his friends when the two engage in good-natured sparring.

Some members of Prophet's gang stop off at a gas station where they abuse the attendant until they are beaten up by Olie and his army buddies.
