Five Greenshirts play a prominent role in the Devil's Due G.I. Joe issue #17. Flashbacks show general training for the recruits, with special focus on Corporal Eddie Shrote. At first they think it will just be a repeat of boot camp, which all have gone through before. They soon learn it is much more, as G.I. Joe basic training involves live fire. Beachhead takes them on a dangerous mission deep into a hostile city. The team learns to work together to accomplish their goals, up to and including disobeying direct orders. Many Greenshirts get half-satirical code names throughout their training, but Beachhead's squad gets simple numbers.
