Widger,
You get the point
It just seems a pathetically childish action to take with someone who is at the top of their game.
The fella would be a better sub commander because of the accident, not worse, he becomes even more potent. Everyone learns from their mistakes, I don't see why people in top 1% would be any different.
There won't be a decent reason for his 're assignment', it's purely service 'mentality' dictated by people with zero common sense & no balls.
