Recently re-watched "Starship Troopers." The movie is cool, but I've always wondered - why is there no military equipment? No tanks or IFVs.
So, this is one of the types. Unmanned. For example, to support infantry or cleaning the area. Two exchange machine gun, one automatic gun on the turret and rockets for extra large bugs)
It might be because the soldiers in the book had power armor that allowed them to hop around the environment. But don't take my word for it as I only read part of the first chapter.
