Trappa
The Feral Orks have their own answer to Kommandos and this time, they have literally gone commando (As in the butt naked type). Trappas are basically Ork Vietcongs or Catachan Devils, and they are as awesome as they sound.
Overview
Trappas are Feral Orks who are specialists at gathering meat and furs from their homeworld's native fauna for the rest of the tribe. Whilst certain Feral Orks such as Huntas prefer to hunt their prey face-to-face even if it is a monstrous creature, Trappas are more sneakier and cunning, preferring to ensnare their in a safe and cost efficient way. Of course this action is considered quite un-Orky, but it seems setting traps seem to gain more game rather than charging in and bonking heads, so the rest of the Feral Orks have to deal with it lest they starve to death.
In times of war, they are excellent at sneaking up on their enemies and set traps for them many solar days in advance. To a Trappa, there is very little difference between a non-intelligent and intelligent creature, all are considered as equal game, only that this particular form of prey just so happens to be capable of shooting your face to pieces from afar. They use three different basic yet often deadly traps, known as Bang Traps, Fire Bombs and Punji Pits.
Trappas often wear thick pelts of fur, skinned from particularly vicious animals they have caught as trophies. Trappas occasionally form a mob of five to ten and are as quiet and reserve as their space counterparts. Heck, Trappas maybe the only few Orks that is able to NOT stand out like a sore thumb as they usually inhabit extremely dense forests, in which their natural green-colored skin would help a lot.
