When I was 18, I gave some thought about joining the military, though I wasn't willing to put up with the many personal sacrifices it requires. Though if I were to have joined, it would of been the Air Force. I'm quite disappointed that the Air Force is forcing an atheist sergeant to leave in a few months if he doesn't say "so help me God" in his oath.
From what I understand, Air Force troops could omit the "so help me God" part if they wanted, but a small and quiet update now doesn't allow it. It's funny that the same oath requires everyone in the Air Force to support (and defend) the U.S. Constitution. The Constitution guarantees religious freedom and also prevents religious tests for roles in government. So the people enforcing the rule are actually not supporting our U.S. Constitution. Hopefully President Obama or Congress can get rid of the rule before the man is told to leave in November.
