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.
