Stupidity: An explanation is given for the reason why the bombs planted on the Gundam are not activated by remote control (they have plastic explosive in the regiment but not remote controls!), but no reason why they set the timer for the explosion to 30 minutes, way too much to be of any use in combat against the Gundam. Moreover, if the vulnerable spot of the Gundam shield were situated where it explodes at the beginning, it'd be completely useless.
Stupidity: The Zeon commandos who plant the bombs on the Gundam correctly identify Amuro as the pilot. The Gundam is completely defenseless and pilotless during the whole bomb removal process - they could attack at any point and make the bombs explode shooting them like they did for the first one, but they just don't.
