SPHA-T
this was the Self-Propelled Heavy Artillery-Turbolaser vehicle designed by Rothana Heavy Engineering, first used by the Old Republic to support the clone troopers of the Army of the Republic in the Battle of Geonosis. Theywere used to deploy up to twenty troopers in an effort to augment the forces of the Jedi Knights in fighting against Count Dooku's droid armies. Each thirty-four-meter-long SPHA-T stood just over twenty meters tall, had modular weapons emplacements, and could be armed in response to its target. The basic weaponry consisting of a heavy turbolaser cannon and twelve anti-personnel blaster cannons which protected all sides of the vehicle. Instead of using a turret to move the turbolaser cannon into positon, the SPHA-T had twelve articulated legs that quickly manevuered its bulky form into the correct position. The complex system of legs could also moved the vehicle at speeds near 35 kilometers per hour. The turbolaser cannon could be replaced with a heavy ion cannon or concussion missile launcher, while the smaller blasters could also be changed out for anti-vehicle laser cannons or grenade launchers. Each SPHA-T required a crew of fifteen troopers to operate, which included ten gunners. Much of the vehicle's interior was given over to the powerful reactor cores which powered the weapons systems. The reactor core caused a good deal of trouble in those battles where the SPHA-T's hull was breached, since the core exploded in a massive fireball that caused huge amounts of collateral damage, often to friendly troops.
