Thrust,
I'd be in the same boat brother. From a personal standpoint the family and I would more than likely take the 2 year'ish Leave of Absence from the Reserves. I believe you and your family still keep your Reserve Tricare Select and Military ID's (so the plan would be to take the drivers test for free at one of the Military Bases). Commuting back to the states once a month seems hard both in time, money, and family life.
