Baker Team was the codename of John Rambo's special forces unit in the Vietnam War, headed by Colonel Sam Trautman. It consisted of eight members, all of whom except for Delmar Barry, Rambo and Trautman were killed in action during the war, in various, horrific ways. Barry later died of illness from the war's poison gas. As a tribute to Baker Team, Rambo machined the grooves on the top of the Rambo III Knife to represent the men that were killed. The big groove was for Barry because he was closest to Rambo and also the largest guy on the team.
