At the risk of sounding too cynical...
I would not list military experience at all on your civilian applications. Not all, but some PDs, may have a prejuidice upon military applicants for several reasons, such as may be pulled from the match, own military views, unlikely possibility of getting called up from IRR or prior bad experiences as examples. Some of these may be irrational thinking, but it is hard to change people's opinions. On the other hand, there may be a PD that views military experience as a bonus. I have certainly met a couple of these both types, even though most are neutral. Given this I would rather avoid turning program directors off based on my military background over an extra thing to put on your CV. It is hard to tell who you dealing with beforehand.
