So in reference to Dvorsky's article about LOX and a piece of burning charcoal a friend of mine pointed me to this wacky 70s Navy training film gem:

The film starts out played for laughs, and also plays well to the brief attention span of young military men and then ends with stark, brutal honesty just to underscore the point.

I guess that's the hallmarks of a good military training film. Probably would never get made these days and for good reasons!
