McGillis has some trap card for sure. It seems he found something on Mars that will turn the tides.
It's hard to think of McGillis has some mastermind anymore, given that his whole plan on retaking Gjallarhorn relied on everyone respecting the Gundam he pilots. But I have been wondering why they introduced mobile armors about 10-12 episodes ago, and whether they will at all be revisited again in the future.
