The Great Gundam Project 21: Mobile Suit Gundam 42 & 43

Here, after a whole year of fighting, two men stand facing on the edge of history, so close yet so far in their tragic fight against special boys in special robots becoming the totality of human existence. How little they know there are four decades of this yet to come. But there is yet hope, in the dying of the war, in the flames of battle, there is one yet brave enough to proclaim the truth: the robots don't need legs in space.
