This article describes a feature in the first Apocalypse Rising
The White Rambo Shirt is a clothing item found in Apocalypse Rising.
The White Rambo Shirt is considered a step up from the White Civilian Shirt; it is slightly harder to find than the regular civilian shirt and shows that whoever wears it has some experience, even if not much. This shirt is one of the least stealthy clothes in the game. It's white coloring makes it impossible to blend in with much in the environment and only few structures would make it useful. Unless you are going for a certain look on your character, like makeshift snow camo, it is not recommended that you wear this shirt. The main differences between this and the White Civilian Shirt are that this is short sleeved and has gloves, so it blends in a little better. When it is on the ground or in your inventory, it's clothing "block" is brown, although the shirt when worn is white.
