Probably because they're looking at the Army, Navy, and Marine Corps, where morale and reenlistment rates, especially of the most useful sorts of people, are relatively low. I guess the Air Force and the Coast Guard are the place to be.
I just heard on the radio that Navy re-enlistments are very good. It seems that RCGirl has posted some encouraging items about Army re-upping, but I can't recall exactly what those said.
It seems to me that the FRAUDcasters are probably at it again.
