I have to admit I hate the idea of Greenshirts in the comic and/or the cartoon. I think there are more than enough named Joes that Greenshirts aren't needed in those mediums. Unless they happen to be in the background guarding the instillation or handling support duties.
But, as toys, I like them. I use them in places I don't want to use a named Joe, like gunner stations on vehicles, guard positions, manual labor, etc...

My Greenshirts manning different areas around the ROCC.
I know there are plenty of classic Joes we'd all like to see first, but I think there is room for more Greenshirts.
We already have the basic cartoon Greenshirt, but I'd like to see the following:
1) Desert Greenshirts (Brownshirts?)
Easy way: Same Greenshirts we have except with brown pants and tan shirts.
I'd rather see Dusty bodies w/ different heads.
2) Urban/Night Greenshirts (Blackshirts?)
Easy way: Same Greenshirts we have except with black pants and gray shirts.
I'd rather see Comic Pack Firefly bodies (including the vest) in black w/ different heads w/ knit caps. Use black helmets if it costs too much to add knit caps to existing heads.
3) Arctic Greenshirts (Whiteshirts?)
Snow Job bodies w/ different heads. Use Parka Snake-Eyes backpacks.
4) Navy Greenshirts (Saltshirts?)
Easy way: Shipwreck bodies with different heads w/ sailor caps and new hands. Include life jackets and use white helmets if it costs too much to add sailor hats to existing heads.
5) Pilot Greenshirts (Flyshirts?)
Easy way: SRO Ace bodies with different heads. Put in a mix of fighter pilot helmets and helicopter pilot helmets.
I'd also like to see more of a military Greenshirt as well, and get rid of the Snow Job rifle and put in M-4's, a SAW, and backpacks. Use boonie hats instead of helmets.
How does everybody else feel about Greenshirts?
Want more?
What areas?
