Absolutely! Some people just can't handle the Marine Corps - too tough.
Again, not a slam on the Marines.
Some people have more to offer their country than sitting on a tank shooting at people. There are other jobs that are just as honorable and needed. Someone, such as myself, had to ensure that air control computer equipment worked so that the Air Force could provide the Marines with air support.
I was in the Air Force but was never a pilot. Does this make me less of a man?
All branches of the military serve a purpose and are honorable.
