Heavy Artillery Gun

The Heavy Artillery Gun (HAG), or mortar tank, was a mobile repulsorlift artillery piece used by the Trade Federation and, later, the Confederacy of Independent Systems. In its early stages it superficially resembled the Trade Federation's Multi-Troop Transports, though later configurations would instead echo the appearance of the Armored Assault Tank.

Description
The HAG's artillery cannon had tremendous range, and was lethal to the Galactic Republic's Republic Troop Transports and walkers.[2] It had heavy armor which made it pretty resistant to laser cannons, but not to bombs - though it could still survive a few direct hits with bombs[1], but very poor speed and maneuverability, which allowed it to be destroyed fairly easily by faster and nimbler Republic vehicles. During the Clone Wars,[2] it was used as a lighter equivalent to the Republic Self-Propelled Heavy Artillery units.
