I am on officer in the Reserve, and take off when I need for Guard Duties, usually only 4 weeks a year, because I am off on the weekends anyway. They cannot dictate when and how you use your military time, unless you fail to provide your written and signed orders to your supervisor or manager. I am in management myself, along with two driver supervisors who are also in the guard, I sort of like the fact that one weekend a month and at least two weeks a year I get to boss them around! I work as a PDS, and they always try to screw up our plans and stuff, so it is great to work them hard for once.
