Welcome aboard!
It's good to see another Aussie in the ranks. I can recommend that you download SH3-commander, a nifty little program that lets you adjust all sorts of things - including the fatiugue model. You can turn it right off. No more sleepy soldiers on board.
Just run a search through the forums, and I'm sure you'll find a download link. That is, if somebody doesn't post one here first.
