Siege tanks are strong against marines and hydralisksand weak against thorsimmortalsand zerglings. The siege tank bobs slightly when it stops moving. It is also highly vulnerable to air units.
While in 'siege mode,' the tank cannot fire at 'point-blank' range this 'dead zone' leaves the tank vulnerable to attacks by melee units. The siege tank continues to function as it did in previous games with the dual tank and artillery modes, except it doesn't require as much support as is needed in the original StarCraft. It is voiced by Matthew Samiareprising his role from StarCraft. The siege tank provides the terrans with a marriage between armored infantry support and mobile, long range firepower.
