Yes, but I’m hoping to limit the time away from my family to 30 weeks.
I’m joining the Navy Reserves, which is a bit more flexible than joining the Navy. My wife and I currently work on a Navy base as civilians, so I hope to do most of my drills and duties there, and still be home for dinner every night. We know of a couple people in similar situations that do this already.
Boot camp is 10 weeks long. Tech school, which needs to be done immediately after boot camp, is something like 15 - 20 weeks, depending on your job. With any luck, this 30-week period is the longest that I will be away from my family. It will suck, but everyone has been very supportive.
Once I get back, the goal is to find a full-time duty close to home so that I can start maxing out the GI Bill. I’m told I need 3 years equivalent of active duty to Max it out. After that, I may drop back down to one weekend a month, two weeks a year.
Navy recently raised their enlistment age cap to 42. They’re currently the only service to do so, that I know of.
Edit: As far as I know, the enlistment age cap for most other services is 39, and the officer candidacy age cap is 35. There’s variations and waivers though, depending on your situation.
