HI A.,
My hubby has been in the military for 23 yrs. He is currently in the reserves. The reserves are completely different from active duty. The socializing and stuff on the base is pretty much all for the active duty families. You may be invited to a function or to once or twice a year maybe but that's it.
There are some great benefits. Tricare Reserve select is inexpensive healthcare where the govt has negotiated much lower rates for everything as long as you stay within the network. Not all hospitals participate so you will pay a % of the normally charged price if you use a non-network provider/hospital.
Military id where you can get lower rates on zoo tickets etc
and of course the extra money.
Reserve jobs vary greatly depending on what he's signing up for. Make sure you both have an understanding of his deployment schedule or his deployability. Depending on his skills they should be able to give him an idea as to whether he will be a weekend warrior unless all hell breaks lose or whether he will be deployed overseas and for how long, rotation.
If he is deployed there really isn't much organized help from the military if u need it while he's gone so being totally self sufficient is the only way.
Anyway hope this helps.
All in all the military life has been great. I think i like active duty better than reserves but its still great. He will miss out on stuff but we just make birthdays a week later or do father's day when he gets back.
Good luck
