Not yet. I have a nephew, Chris, in the Air force and I believe he will be going before too long. He is still in training right now.
His father is in marketing and makes a very good living with a large company. When my nephew said he wanted to join the military, his father expressed some concern. His father had hopes that Chris would go to college and go on to get an MBA.
Chris said to his dad "You would think that would be the safer route, but that's the route many of the folks in the twin towers took". He said "at least if they come after me, I will be shooting back". Chris tried to join the marines as soon as he graduated from HS, but he had a hernia. They wouldn't take him until it was repaired. He ended up going to college and going into the Air Force through an ROTC program.
A nephew is not the same as a son, I know, but I do love the kid. I don't see it as a burden. I don't think my sister does either.
We are military brats though. When we were little, we knew our dad could be in harms way. We had friends who lost their fathers. It wasn't a burden. It just was.
It can't help but be a worry though.
I salute you for successfully raising a wonderful human being, who is willing to sacrifice so much for the benefit of others.
