Marine veteran Robert "Bobby" Biers recalls more distress as a drill instructor dodging comments from mothers than when he was on the frontlines in South Vietnam.
"I had these mothers calling me up, asking me, 'what did you do to my baby? He has manners, and he's polite. He lost 100 pounds. He's lean, mean and tough,' " Biers said.
"Tough but firm" is how Biers described the Marine Corps' approach to making new Marines.
