Anthony,
I didn't get that from the JAG Major's post. I think he is emphasising differences between "punishment" and "corrective training", as well as the legalities and/or illigalities associated with them.
I think the JAGMAJ brings up a valid point. Anyone but a commander administering "punishment" is overstepping their bounds. Punishment as in "non-judicial" is reserved for commanders.
That's not the case for proper "corrective training". It is a viable option for non-commanders, as long as it does not become "punishment. As far as I am able to tell from his posting, JAG Major was never against corrective training done correctly,
