To be honest, in Duanmu Huai's view, the battles in this galaxy were simply child's play.
How to put it, whether it was the Earth Federation or ZAFT, or even Oub, there were basically no tactics, or rather, their tactics were all pretty much the same.
Motherships enter the battlefield, then deploy a bunch of Mechas, and then the Mechas engage in close-quarters combat, with the motherships providing cover from behind.
To put it bluntly, if it weren't for the fact that they had Mechas, this would be at the level of a Medieval village brawl.
Of course, overall, the situation of the Minerva wasn't very good. After all, beset by wolves in front and tigers behind, just as Ann had anticipated, as soon as the Minerva left national waters and engaged the Earth Federation Fleet, the Oub Fleet also directly aimed their cannons at the Minerva.
Well, thankfully the Minerva was mentally prepared for this and managed to dodge accordingly.
