Ahhh, the Army act 1955, what a throw back to the 'good old days'. Always remember the poor bastard sapper reported to me for being in debt 'in contravention of the Army act.' Went before the big chair and got fined 28 days pay, and I got a bollocking for alllowing him to get that way. His missus left him and he had no family to look after his kids, so he was having to pay a child minder.
Most offences though are there for maintaining descipline, as without it in combat it leads to people dying. An order given HAS to be followed. Weapons must be cleaned regularly, kit maintained, feet inspected, it goes on, and has to be done. 'Thems the rules, boy, and if'n you don't follow em,you might as well sew you'm into yon maggot an' wait for the ost ta' take yo'm 'ome' as my old OC, Major 'Tash used to say.
The day we lost Crown Immunity was the day the flood gates opened to the PC brigade. Soon it'll be against your 'Uman Rights' to be forced to go to a combat zone.
