Always used to be a month's pay in NI...
... I recall one occasion when a Rock patrol had an ND, with which SAC X managed to scratch the upper arm of Cpl Y his brick commander.
They both got done a month's pay, as the Cpl should have been supervising ....
.... but Cpls get paid more than SACs, so Cpl Y gets a bigger fine as well as a hole in his arm (nearly) ... oh how we laughed....
