Look pal what ever way you look at it he was in the wrong.
Miliatry law, He shouldnt have done what he done with evidence on cam.
There is 100s of cases like this every year, where if you say I honestly belivied my life was in danger and made a split secone decsion.
But there is evedince proved this was not the case.
Its morally wrong for SGT A to be sentenced you know that and so does every one in the country.
Law is the law and I personally think they had no option.
