30 year USAF veteran here who served with, trained along side and deployed with all services. Thanks for your desire to serve but I must make some statements up front.
Not all families are cut out for military life since the demands of the service can put huge strains on marriages. Some services are better then others but it cannot be compared to a 40hr a week civilian job. To be successful, you must look at military service as more than just a job/occupation. You will be trained to perform a specific skill or a combination of skills. Whether you are an air traffic controller or an infantryman, often, you will be required to perform those duties more than 40 hours a week. The military can work you everyday of the week. There is a reason military members earn 30 days paid leave a year. I have been retired for 6 years and work as a weapons instructor/weapons repair guy for the USAF. I'm the only civilian in the shop and the 5 GIs I work with routinely work 10-11 hr days. They get most weekends off but that's not always guaranteed.
Are you and your family willing to move every few years. If you are warm climate folks, how will assignments to MT, ND, WY go over. If you like rural living, how will an assignment to San Diego or WA DC be handled? I was assigned to 12 different duty locations in 30 years. My first 2 I was single but the wife/kids followed me around for the next 10. We always enjoyed going to new assignments but not all families would view the chance to travel the same.
The USAF learned a long time ago that you recruit the member but you retain the family. Meaning, you must convince the spouses and kids that the AF is a great place to serve and to get them to encourage the military parent/spouse to reenlist and serve 20-30 years.
For both me and my family, we have found that even though the hours were long and deployments/overseas tours can separate you from loved ones, the positives always outweighed the negatives.
Knowing what I know now and if I were to do it all over again there would be very few things I would change. For a young single guy wanting to serve one tour, get some training, life experiences, see the world, the USMC is the best choice. For a married guy, the USAF is hard to beat.
Make sure you gather as much information as possible. All services have their pros and cons, select the branch and occupation (MOS/AFSC) that best suites you, your desires and goals. Remember recruiters are working hard to get #s and they will tell you things you want to hear. They may not be lying to you but they may leave some specifics out. Lastly make sure both you and your wife make the decision together.
Best of Luck
