Comparing angel weapons to Gundam weapons in terms of strenth is useless. AT fields have to be expanded before ANY attack hits the opponent. This is explained in the first or second episode. So no more fast fowarding through plot/explanations please. Thank you.
In other words, it really doesn't matter how strong your weapon is. God invented physics. If he says, no unclean technology touches an angel, no unclean technology gets past that AT Field. Yes the AT field is shredded by EVA 01's hands, but only after the EVA counters with it's own AT field. Conventional weapons would be useless against the god who created them and there underlying scientific principals. This goes for all the EVA's, 00, 01, 02, 03, 04, and the little psycho ones from the movie.
