To me it's a clear “yes” that it would have an impact, but to what extent do we...? You're not going to move bases any time soon.
When it comes to family, most of the folks in the military that I know actually have a family. Working in the military hasn't been a total impediment to having a good family life, but whether or not we can do little things.... Sometimes it's just having that flexibility built into the system where if someone's spouse needs to go somewhere in the military and they can't do it, they would be able to leave the military for a year. They could just say that they'll be out for a couple of seconds, but they'll be right back in. That can help.
As long as there's flexibility built into a career in the forces, you'll find all kinds of ways to give satisfaction to the members of the forces and make sure they always want to come back—that they can't wait to come back.
