Orbital command

The orbital command is an upgrade to the terran command center. It was previously known as the surveillance station.

Overview
After the Brood War, the increasing use of command centers in combat zones led to the development of standard schematics for upgrading them to a dedicated military role. The orbital command upgrade allows space assets to better assist ground forces.

Game Unit
The orbital command may summon MULEs to aid mineral harvesting. It may also permanently increase the supply generated by targeted supply depots. This is in addition to its ability to clear the fog of war from a small area temporarily, analogous to the ComSat station in StarCraft I.

Once upgraded, it can lift off, but it cannot be downgraded back to a command center or converted into a planetary fortress, but it continues to produce SCVs normally. It cannot be salvaged.

Abilities
None of the orbital command's abilities have a set range. They can be used anywhere on the map.
