I've gotta second this one!! Lets not get political here, regardless of how your political or personal views are, these are US soldiers and they need your support.
I've been there and was lucky enough to have friends and family that sent many packages of goodies, and when I got one I took the personal stuff out and opened the package for everyone to share in, as did the others there.
You have no idea how good a little treat is to these guys, if nothing more than just seeing a package show up!!! It brings them that much closer to home!
Dig in!
