Don't worry wingcmdr,the dust will be pretty think for a awhile.
Just remember that he will have great support in country as well as moral support from people around the world.
Our experiece was somewhat similar in that after 18 years flying F15's and T-38' with only a couple of years in non flying jobs, our son decided that he should finish his career with a tour in Afganistan flying MC-12W's supporting ground patrols.
We had a few moments during his career but this tour did cause the most concern. We did know that he had the best training possible and the full support of many professionals on the ground and in the air.
He came home safely and retired after a truly amazing career. I'm certain that your son will to soon return and will be thankfull that he has parents who gave him the opportunity and the freedom to accomplish things that other simply dream of.
Please pass on your best wishes, the Skpe service from Kandahar is excellant, and if you can keep us informed of his adventure.
