Yeah, but in the book the Marauders were present way before the Bug War began. They were nothing special when the Bug War began, being standard issue for quite a long time at the beginning of the war.

From what I know of the book. The Marauder suits had no reason to exist until after the Bug War began.

That be like inventing a giant robot to fight Godzilla before Godzilla was even born.
