Why do you want to retire in Germany? Unless you have some cultural ties with Germany, speak the lanuage, German spouse etc. what is the point?
Apparently, he actually
enjoyed the country when he was stationed here long-term. Imagine that.
...you really can't expect the military health system to support you just because you're a veteran.
EH?! If he put in his 20+, he damn well can and should expect the military health system to support him. That is part of the deal for long-term soldiers, and a great reason why many stay in 20+ years. He
deserves it and absolutely should take advantage of it.
Unless you have another means of support, a military retirement won't be enough.
Well, that depends a great deal on his rank when retiring, and, of course, the ever-fluctuating exchange rate. But if he was, let's say, E-9 or higher in the Army, or an officer of any rank in any force, he could live a simple, but rewarding retirement in Germany. Especially if he retires near an active base and can take advantage of the PX and commissary, etc. And he apparently gets VA comp on top, so it IS doable, on a budget.
Svarazics - browse through the topics in this section -
US Military - and you will likely find a lot of answers, even to questions you didn't even think to ask. I think it is lovely that you would like to retire in Germany, and at the same time, it is good to consider what you would like to do with your time (i.e. work part-time on base, perhaps study German, travelling, etc.) and find a place near an active base where you can take advantage of both the base offerings and the local offerings in your areas of interest.
Do you have a wife/partner who'll be joining you? Would be good to consider her interests and needs as well.
Good luck to you!
Edit: Just looked at Svarazics' profile... says he's 38 years old, so if he joined up right at 18, he'd be hitting 20+ this year. But just to clarify, my comments are based on a 20+ soldier's benefits.
