I would like to contact some old Army buddies I knew 10 years ago and see how they’re doing… in most cases I only know their names. I think I know units for a couple of them, and I can guess what rank they might be. I tried calling their units, but the only information I could get is “That battalion is not in town right now. Try again later” (couldn’t even find out if “later” meant next week or next year).
All I want to do is send the guys a letter or email. Is there any way to do that without violating national security?
