"a RPG delivers very roughly a million times that amount of energy"
Your workings still don't show that !
It mght well deliver a million times the power over the tiny timescale of a detnation but by your own calculations it still only delivers ~ 1MJ of energy. I'm not disputing the fact that a RPG will make a big hole in things ( and indeed in my lab days I've had very small amounts of material do suprising damage)
Biting the hand that feeds IT
