I picture the WC ground fighters akin to the generic type of beefed up armored Marines with bulky rifles of multiple caliber, like in Starship Troopers, Aliens, Space: Above&Beyond... Dekker better get with the program...
Oh, and I love that one single shot gets through Starship Troopers armor, (when Racszak, I forget how to spell it, snipers the one marine who's being eaten), and also how it doesn't seem to stop the bugs... So why not just run around in T-shirts and save the weight and bulk? Armor never works in movies anyway... Just look at stormtroopers...
