Tanker Bug

The Tanker Bug is an enormous Arachnid variant that appears in the film Starship Troopers and also the CGI TV series Roughnecks: Starship Troopers Chronicles. These giant beetles serve as armoured assault units in the Bug army and are capable of swiftly decimating whole platoons of Mobile Infantry.

Overview
The Tanker Bug is a giant beetle native to Klendathu and is one of the most powerful types of Bug in the Arachnid horde. It stands roughly ten to eleven feet tall and over twice as long, its large body being supported by six sturdy legs. The Tanker's body is covered with extremely resilient chitinous plates that are very difficult to penetrate even with prolonged rifle fire, making them tougher to kill than other Bug types. As well as being able to crush human soldiers with their sheer size and weight, Tankers are also capable of spewing a highly corrosive fluid from nozzles on their heads. They ignite this fluid with a spark generated between two small prongs on either side of the fluid nozzle; when ignited, the fluid can swiftly melt down multiple human combatants in one discharge.

While certainly powerful, Tanker Bugs are not without weaknesses. Precision strikes at the gaps between their armour plates can inflict greater damage and they are vulnerable to high explosives. One effective tactic that Mobile Infantry have used against Tanker Bugs is to get atop a Tanker from a raised foothold, shoot the area immediately behind the Tanker's head and lodge a grenade into the wound before jumping off the creature's back.
