I don't know if this is just a BBC Scotland thing, or if it's nationwide but I stumbled upon it last week, and found it funny. It's called "Gary Tank Commander" and it's on iplayer if anyone feels the need to see more of it.
Some folk - well, internet commenters(!) - seem to think it's inappropriate in the current climate, but I beg to differ. I doubt the boys in the army would take offence. It might be different for firemen if they watch episode 2, right enough.
