Siege Tanks (StarCraft)

Good day, Commander.

The siege tank is the backbone of the Terran ground army. It can fulfil two roles: mobile armoured support and stationary long-range artillery.
When unsieged (tank mode) it acts as a conventional tank. It uses relatively light but quick firing twin 90 mm cannons.
When sieged (siege mode) the tank transforms into an artillery gun. It uses an 180 mm shock cannon with far greater range and area damage but with slower rate of fire. In this mode the tank loses its mobility and cannot target its immediate surroundings.
The tank may change between the two modes at any moment. However, this takes some time during which the tank cannot fire at all.
Despite their tremendous fire power siege tanks need infantry support. Marines should be used to keep them safe from enemy air and fast moving units.

This mission will bring you to the small Terran outpost of Boshulya. In its centre you will find two siege tanks: one in tank mode (mobile) and one in siege mode (stationary artillery). Read the instructions for the waypoints for finding the coordinates of the target.
The target itself is embedded in the ruins of an ancient Xel'Naga structure of unknown purpose. It is outside of the base but well within the firing range of the shock cannon. You need to get a visual of the target in order for the sieged tank to shoot at it.

Give us your best shot!
