SCV (StarCraft II)

"SCV good to go, sir!"

- Terran SCV

The SCV reappears in StarCraft II.

Game Unit
Five SCVs can be held at a time in a command center or planetary fortress (upgraded to ten with Neosteel Frame).

SCVs can patrol, a very useful ability considering they can auto-cast repair. While multiple SCVs are able to simultaneously repair a unit/structure, only one SCV can construct a structure at a time due to reasons of balance. SCVs may repair any allied unit that is considered mechanical regardless if it is terran or protoss, but they can only repair terran structures. It is the only terran multiplayer unit without a ranged attack.

Wings of Liberty Campaign
In StarCraft II: Wings of Liberty, SCVs appear from the second mission, "The Outlaws", Raynor's Raiders already having access to them. Later in the campaign SCVs can be built in pairs.

Co-op Missions
Rory Swann gains the following upgrade to his SCVs in Co-op Missions.

Development
Early versions of the SCV had a blue exhaust instead of the current orange. This was not correspondent with the player's color.
