I think everyone know the work Celtic Wolf is doing for the troops cooks but I wanted to make mention of a situation that people might not be aware of.
While the larger active duty (regular Army) units get a lot of press when returning home there are plenty of National Guard and Reserve Units serving over seas, and due to their smaller size they often go "unnoticed" to all but local press.
For some of these troops it's even rougher because they often come back and have to jump right back into their civilian job without as much time to "decompress" and obviously they have to deal with getting called up going the other way too.
I'd urge you to get to know some of your local units and see if they have people over there. I try and help out with some of these local events here like the one where 40 Ohio National Guard Special Forces troops came home.
Here's the press page for the Ohio National Guard for an example. As you'll see there are plenty of smaller units fighting the good fight. I know there are plenty more in each state out there. These are also the same folks that might be there to help you in a natural disaster too.
