Demoted: One general, from BG to colonel.
This is a tremendous punishment in the military--it required personal approval from the president.
Discharged: One captain, one 2nd lieutenant.
Since this is "other-than-honorable" they're not just losing their jobs but also picking up conviction that will seriously restrict future employment. Oh, if they were active duty they may be losing their house as well as their job.
Awaiting Court Martial: Three captains, two 1st lieutenants, two chief warrant officers.
These are guys either unwilling to plea bargain or about to receive punishment worse than they could get in one. Probably the latter.
Article 15: One colonel, two lt. colonels, one major, one captain, one 1st lieutenant.
This is the "plea bargain." You accept punishment rather than go to a court martial.
Letter of reprimand: Two lt. colonels, two majors, five captains, one 1st lieutenant, one 2nd lieutenant.
This is probation, effectively. No direct impact, but it probably trashes their chances of getting promoted again. So for any of them active duty they'll probably be on the street in a few years.
The court martials may be handing out prison time to the worst. The rest seems reasonable for severe negligence. It's certainly going to make it clear to the rest of the officer corps that they will be responsible for what the troops do on their watch.
