I forgot to update this.

El Paso co Sheriffs Office only requires your active duty orders if you are currently on active duty. I have a Colorado DL, I am unsure if there's a difference if one has an out of state license. I would assume such a person would have to show orders placing hmself on a local post ( i.e. PCS order to Ft Carson) and mil ID, like a local gun transfer. But I havent a clue if this person would need additional training documentation (i.e. pistol qual card).

From my personal experience, active duty orders suffice with colorado DL if you're active duty. Nothing else required for training. No proof of pistol qual req. This info is accurate as of July 2011.
