What's your best example of high-speed & low-budget training?

Some time ago I participated in the Best Sapper competition. One of the stations had a GP Medium and a CLS bag in font of it. The OC says, "Take the bag, go inside and react to what you see." Inside the tent is no light, a boom box playing some kind of death metal, and 3-4 casualties with various wounds thrashing around. The task is to stabilize the casualties and CASEVAC the most critically wounded. On the other side of the tent was a concertina obstacle field to navigate.

That was one of the coolest pieces of training I've ever participated in. It was low budget and a squad could do it. I think about that a lot and compare with the times I've seen first aid training be a crate of old pressure dressings and a green skill level 1 book that someone is reading out of.
