Starship Troopers 2005

Maybe someone remembers this game.The question is what is there in the game, the mission where you have to sneak through an abandoned factory and find the Marauder and then quickly skedaddle to the landing site.Is there somewhere a mention of why this worked was with a nuclear warhead?Just wondering, maybe somewhere it is mentioned?Well, actually, who sent him to this abandoned factory processing nuclear waste.
