Re: So when can we expect
Here's a hint, it's very hard to train someone to shoot-to-maim. You teach them to aim at the centre of mass, because it means they're most likely to actually hit the target. It also means they'll probably be dead because that's where the vital organs are.
Ironically if you could teach troops to shoot-to-maim you would because every injured troop requires another one to carry him off the battlefield. Dead ones can wait.
