Minus 30 something, wow that's cold. I've just thrown another peasant on the fire after reading that.
Maybe Blighty's not so bad after all. It's been freezing today but was working with coat off and sleeves rolled up the other day.
Does the cold noticeably affect the lock time of your guns when you're out in those sub zero temperatures or do you keep your shells in your pockets to warm them ?

Rust never sleeps !
