Great Falls is close to all of those species. I don't know the residency requirement or rules for Active Duty Military so I cannot tell which districts.

Camo, who need any stinking camo, unless of course you are a bowhunter. You must wear 400 inches of hunters orange if you are a rifle hunter.

This is a very good local Montana company that makes camo designed for Montana. http://www.ghostcamo.com/ I can attest to the Prairie Ghost and Snow Ghost patterns as being very very good.

Also Great Falls is top notch for waterfowl and close to great upland as well.
