What can I expect at Fort Belvoir (WTB) as a wounded soldier?

When I was there you could expect to focus on your wound first, I don't know what's going on now but I would assume that it's the same, let us know.

SPC Jeff Diggs, at the WTB your sole responsibility is to heal and go to your appointments. Now depending on approval and your plan you may be authorized to get an internship or take courses while you are there. I recall have to do PT still but it is not your standard PT. Make sure you take this opportunity to heal. The by no means, means that you are being removed from the army but that they are going to give you time to heal. If circumstances allow and should you want you may be able to return to active service if you are cleared by the MEB
