Dollar General Shipwreck green (or blues if they are at sea) and the Duke either color green or grey (Night Force).
Retaliation: Beachhead, Ultimate Flint, Ultimate Duke and the Troopers.
Renegades Duke.
POC Clutch, Steel Brigade Delta.
Also, Firefly from the 50th and Retaliation 3 packs would make excellent Night Force "Greenies". (Just a simple headswaps, or if you have a ton of Channing Tatum heads swap and pop and there you go.)

That's a really good looking custom. I'm stealing this.

:D :D :D

If want your Green Shirts to be Camo instead of flat green, the POC Stalker is perfect. One of my favorite looking figures.

I used to use the pea soup green beach head from the Spy Troops days (cuz the olive green was the beach head I used as, uh, Beach Head).

Ah man, you folks have me looking all over the internet for these things! I think my favorite, so far, is Retaliation Beachhead - simply because I could pop any head on him without having to paint / replace hands and necks.

Have fun!
