This one can be tricky - obviously, some legitimate military members are looking for romance. Check the rank on the uniform (you can search online to match it), and ask them what rank they are. Ask them what they do for the military. Search to see if their image matches someone else. If their writing sounds fake, it probably is a scammer. I was once contacted by a guy with four stars (all 4-star generals are listed online), and he claimed to be a surgeon. I played dumb and asked what his rank was, and he said he was the "Surgeon General." Uh, not quite. I found the image of the real person and informed them, and Facebook eventually deleted the guy.
