Here's the thing, only DND can use the actual combat pattern (the pattern used to make the uniforms, not CADPAT). Civilian companies can use real CADPAT, however they need to get permission from DND first and it can NOT be in the form of an issued item. However, if you take something like Mountain Stalker (or one of the many lookalikes) you don't need to get permission from DND (as long as you don't copy the combat pattern).
