I'm not sure if there is an exemption for active military, if not this applies.
If you are a legal Michigan resident, you must get a purchase permit and register your handgun here (MI). You can than legally possess the handgun for all lawful purposes. In Michigan if you do not have a CPL you must transport your handgun unloaded, in a case in the trunk. When you get to your destination you may then load your handgun and OC in all lawful places. You CAN NOT posses a handgun without a CPL in these places listed in 750.234d unless you are the owner or you have permission from the owner. Premises include parking lots.
