I remember seeing something on TV, a "documentary" of some tacticool training. They were to throw themselves bodily away from the grenade, feet towards it, and cover their ears with their hands while opening their mouths. Then the footage showed these trainees at some social event, black tie and martinis, and a mystery object gets tossed at their feet. They all do as they were "trained," and their trainer appears from the sidelines to talk about how well they did.
Without commenting on whether the tactic is sound or not...
What bullshit! Talk about training for the 0.0001%! In what possible scenario will any of us ever have a grenade thrown at us? And, should that infinitesimal percentage event happen, what are the odds it will happen in such a way that we both A) recognize it and B) have time to react?
I really hope I get paid as much as these asshats some day for advice that is every bit as fucking useful!
