Spec Ops clothing has two variants. One variant has a black beanie and M85 Woodland camo pants, U.S. Woodland Marpat BDU. The second (pictured) is a marsh-coloured, Partizan-type pattern with an OD green bandana.

Both are very useful in Chernarus and can be found in medium/high value military loot spawns and crashes.
