Yuki: Actually the example I set doesn't assume anything of a sort that's just your impression of it. I'm quite aware that they'd get shot a lot but I never assumed that they were going to fly through it until the end of it, it's not like they're only able to fly they have legs and they can move pretty fast on the ground as well. I took that into consideration and frankly whether they stand still or try to move the bombardment wouldn't change. But like I said for the third time now Hallelujah managed to stand without screaming like a baby while getting bombarded so it's not impossible to actually do that, the possibility of standing through a bombardment and then move exists.
Also I never claimed the plan would work, just that in my opinion it's a chance for survival without sacrificing any units and without getting your ass handed to you for more than half a day. Here's another thing that teamwork could do, Dynames needs a little time for sniping to aim etc and his defense isn't the best at those times. So what would happen if he just takes cover under Virtues GN field? First he'd get defense plus it shouldn't be impossible for Virtue to move while having that field activated. Secondly with communication they could drop it for a second just so that Dynames could snipe at whatever. You can have Exia and Kyrios try and secure a way in the front. As long as Exia is on the ground and uses it's mobility it gets harder to hit him of course it's not like he can escape everything but he'd be able to evade some or most of it while moving forward plus he's got a shield to help block after all. Kyrios I'm more unsure of but it's not impossible that he can guard and move forward. This of course requires the Gundams to met up but like I said teamwork, which the Gundams for the most part haven't displayed.
If someone gets hit so they fall down it's not like they can't fight back in that position and teamwork does require you too look after each other so you'd have for example someone shot anyone trying to grab which ever Gundam it is. Not to mention if someone falls from the bombardment there are three options for the enemy to take two of those options work in favor of the Gundams. One would require the enemy to fly through the bombardment to the Gundam in order to secure it so unless they're good enough to evade every shot they will get shot and that's not good for them. Second would be to stop with the bombardment which gives the Gundam more time to regroup and act which isn't good for the enemy either since they can advance pretty fast while they're not shooting while taking down incoming enemies. Third would be to keep up with the bombardment which basically means nothing changes so it's just the same status quo as before which isn't exactly a bad thing either.
Another thing about this that's good is that the Gundams aren't spread out which means that there's chances that the three forces start acting and getting in each others way. It didn't look like they were working with each other as they were taking down Gundams on their own but if say one Gundam get hit and fall to the ground and the HRL and Union want to go in and secure the Gundam while the AEU keeps up it's bombardment their forces are about to get hit. All three want the upper hand on the other so chances of them getting in each others way aren't impossible. They may even start fighting each other over it which of course goes against CB principle but hey if they d that just shot them.
Like I said it's a fighting chance at the very least and as long as they get to the base they'd have more than a fighting chance plus they'd probably be able to do it in far less time than standing still for that long seeing as it also requires some swift acting.
