The Grey Rambo Shirt is a clothing item found in Apocalypse Rising. It can be bought at the spawn screen for one credit.
The Grey Rambo Shirt is a variant of the Rambo Clothing. It is easily recognizable by its brown gloves when spotted. It is considered to be a step up from Civilian Clothing, and shows that the person who wears it is at least a little bit experienced. This color does actually help you blend into the night, but will be a dead give-away in the day. This is usually used by people who wander around at night. The main difference between it and civilian clothing is that it is short sleeve and has gloves.
