The Green Rambo Shirt is a clothing item found in Apocalypse Rising. It can be bought on the new spawn screen for one credit. It can be found as a brown clothing item for 1 credit.
The Green Rambo Shirt is considered a step up from the Green Civilian Shirt; it is slightly rarer, and shows that whoever wears it is an experienced player, if only slightly experienced. This shirt can blend into the environment, but still noticeable since it is lighter than the grass. The main differences between this and the Green Civilian Shirt is that this is short sleeved and has gloves. When it is on the ground or in your inventory, its clothing "block" is brown.
