I'll spare you photos of all my kommandos, I feel that this one shows the style best. His cloak is put over his choppa (held in a stabby fashion) and his slugga as to disguise their shine from prying eyes and hide his outline.
All my Kommandos have knives rather than motorised choppas or axes. The knife is better for stealth and is silent opposed to motorised versions. This is seriously advanced thinking for Orks, hence why these guys are allowed to get close to the enemy first since hopefully their lack of orkyness will get them killed.
