I’m not sure. Training is not to be compared with actual torture.
I’ll have to consult my sibling, who’s a retired soldier.
Waterboarding is waterboarding. Is it, or is it not, "torture".
Personally, I find it impossible to consider waterboarding as torture, since:
1. We do it to our own. And we wouldn't submit our own troops to torture, would we?
2. There is no intent, nor risk, of killing -- or even maiming -- the subject. The threat is totally psychological. In my view, torture is a process that either maims or kills its subject.
