These guys serve everywhere throughout the Army (not sure about the Marines). In Afghanistan, we had an EOD bomb tech with a prosthetic leg. He put on the suit and diffused bombs - it was incredible. With the growing number of amputees still wanting/willing to serve, you can find them everywhere from Battalion Commanders, Command Sergeants Major and even down at the company level.
I think it is awesome that they continue to serve when others whine and cry about why we are overseas.
