Now we have the meat of the matter. What is he guilty of?
1. Disobeying a direct order?
2. Manslaughter?
3. Both?
Here's what's going on...He's guilty of the first, and that's not in dispute. That's why the punishment looks so light. He'll never be able to rise in rank, and he'll never fly again. He's most likely out on his ear when he gets back home, so it's not being 'swept under the rug'. He's also losing 1 months pay, which, IMO, should've been a bit closer to 6 months pay if one looks at the results of his disobedience...however...he has friends, so he's protected somewhat.
