Impeding Assault Tank
The only action the IAT had experienced was during the Battle of Umbara between the Grand Army of the Republic from the Galactic Republic and the Umbaran militia that had sided with the Confederacy of Independent Systems. As the clone troopers of the 501st Legion patrolled the planet of Umbara, one IAT suddenly sprang out from under the ground, catching many clones off-guard. Following the arrival of additional crawler tanks, the Republic forces used rocket launchers and thermal detonators to destroy the vehicles.
