Several Tanker Bugs were seen on Planet-P and Tango Urilla, where they commonly attacked Mobile Infantry forces by tunnelling underneath them and coming up behind the M.I. Tanker Bugs were commonly used by the Arachnids during the Klendathu Campaign.
They are, however, highly vulnerable to explosives. A Tanker's thick exoskeleton provides it with excellent protection from common Morita rounds, allowing them to withstand enormous amounts of concentrated fire. With each Arachnid serving a specific military role, Tanker Bugs function as a form of armor support.
