Casper Van Dien must have been offered plenty of loot to reprise his role as John Rico from Starship Troopers. He's now in the officer ranks and still a role model for the infantry troopers fighting the arachnid invasion.
Starship Trooper 3: Marauder finds things have changed in the Federation and on the arachnid side. The original one ended with the capture of a giant brain bug as it became obvious those bugs definitely were using some kind of military strategy. But it's only the tip of the iceberg so to say.
Rico is in a nice jackpot as he's blamed for a huge battle loss and scheduled to be hung. But he has friends in high places and they need him for a rescue mission of a sky admiral.
There's also a growing peace movement that gets kind of violent as peace movements sometimes can.
As for the rest all I can say is the bugs are learning quite a bit about what makes humankind tick.
Van Dien is still as heroic as ever as John Rico, perhaps a bit wiser with age. None of the others who played characters who survived reappear in this. Might have made for greater continuity if they had.
Unlike the first sequel the second paid a bit more attention to the society that formed because of the bug invasion and some of the inevitable flaws in a militarist based society. It's also got a lot of good action.
Nowhere a patch on the original but far better than number 2.
