AA, yes I do about shaped charges thanks for your concern - also the shaped charged would direct the blast inwards. If you re-read my post I also said it that they would knock senseless, i.e. it could incapacitate not just kill the crew, giving the terrorist time to move in and take over - much the same effect as a 'Flashbang' would.
Further more I also stated, if you go back and look, that you would have to do something about the bulkhead wall as well - not just the door.
Yep, at least we agree on the school. Maybe they need to relook at it again, rather than just change its name - make syou wonder if any of the guys we are up against now are grads????
Over to you my learned gun debater...
