I'd be interested if you pull from the book a little more. The movies were nice and all, but it just doesn't beat the MI stomping out swarms of bugs in the Marauder suits. This is a Marauder suit:

The MI is far more powerful in the book, but the bugs are also far more numerous. Where the movies had hundreds of thousands of bugs in a single fight, the book had hundreds of millions in a single invasion. They died a lot more, but had a lot more to throw away. A single MI trooper could take out thousands of bugs before going down, but the bugs could afford thousands of losses far more easily.
