My only concern would be the under 21 military one for the following reasons:

* Very little to any military training is going to cross over to concealed carry, and some would need to be undone in context (i.e., the guy whose only weapons training is .mil and has yet to understand the differences vs carry in public).
* The threat to .mil members seems to be largely on post, if terrorist actions serve as a guide. The state has no authority to authorize CCW on post where the largest target concentration is.
* The maturity of a grunt (or any MOS) when he is in his squad w/ an NCO directing can be impeccable -- decisive, obedient, etc. Out on the town? Maybe not. This, if it passes, will be every commander's headache of the month.
* Most of the guys under 21 are below NCO ranks and live in the barracks if not married. They either don't have the ability to store their CCW piece except in the arms room (good luck getting that out whenever they want) or would have to store it at a buddy's place -- this would violate current CO law and potentially unit/Division rules = nice thought, but impractical. It would be akin to the legalization of marijuana for many guys and gals at Carson, where the majority of under 21 .mil is in the state.
* Why just current and former .mil members under 21? Why not anyone without a criminal history at the age of 18 or over who can pass the required courses?
