There is the real thing you do. You ensure your kids are drafted. However, even in war, there are places that are peaceful that have to be protected. Your kids do have to go through basic training, which is grueling, but once they do that, you just make sure that they're the ones selected to man the supply chain back home. Or maybe they stand in front of an embassy of a third party not involved with the war because you still have to have guards in front of that embassy even though it's probably a ceremonial position.
