Oddly, the only thing that strikes me is his rank, and being in the National Guard. A West Point graduate goes into the US Regular Army (RA), not the state Guard, for an active duty commitment of 6 years minimum. At the end of which time virtually all Army Officers, and every West Pointer, has been promoted to Captain. Even I, a non-West Pointer, made Captain/O-3 at 4-1/2 years from commissioning.
Which suggests to me that Choi had a massive career failure, prior to his gay orientation becoming known. West Pointers simply do not go into the state National Guard out of the RA as Lieutenants/O-2, unless they're thrown out for poor performance, and a failure to be promoted.
So I'd like to learn more about the details of his service. And whether he was using his orientation to mask fundamental failures as an Officer.
I know, I'll get beat up over these observations here. So let me assure everyone I'm against DADT, I'm for gays serving openly in the US military, and I think Choi is helping to keep public attention on the DADT issue. But I still have my doubts about this guy.
