There was never any acknowledgement in the plot of extra, unnamed Joes in the comic. Certainly not an army of them like in the cartoon. Nevertheless, generic-looking troopers in green uniforms that cannot be identified with any named G.I. Joe made infrequent appearances as background characters. This may be an issue with the artwork more than anything else.

Action Force (British) Comics continuity
Greenshirts were part of a team that was tricked into attacking an oil rig belonging to Destro, but was subsequently freed by Quick Kick. They later fought in the battle to defend Action Force's London base when Cobra attacked to free Destro.
- The Greenshirts are named after the Redshirts in Star Trek. A red shirt was the uniform of security officers who had minor or non-speaking roles in landing parties and usually got killed to establish the threat level. Consequently the term "Redshirt" has become a cultural term for expendable background characters.
