Well being in the Army as a single parent would be rough. The judge told us, it is "unstable" due to deployments, hours, etc. Tell your son to go to his Sgt Major and ask for the "parenting plan" this is where he fills out paper work of short time care givers for the kids (30 days and under) and then a long term care giver, one for deployments. If he has this paper work ready and everyone in place and can show the judge that he is putting a "foot forward" and getting everything in line, that might help the "stability" issue of military life. Also, have him check the schools on post and around post where he lives, ensure he get's their ratings, etc and then have him choose the best school and let the judge know that. It's a 50/50 chance with a single military parent...they only thing that will happen is the judge will say "no", so why not go for it, either he get's the kids and/or everything stays the same. I was a single military parent for 7 years.
