Railgun turret

Railgun turrets are a type of defense ordinance developed by the Terran Dominion.

Overview
Railgun turrets were in used by the time of the Defenders of Man insurgency. Nova Terra was able to outfit her ravens with experimental magnetic weaponry that allowed them to deploy railgun turrets instead of standard auto-turrets.

During the End War, Dominion SCVs were able to build railgun turrets in the field.

Game unit
Railgun turrets deal 30 damage in a line when firing, but fire considerably slower than normal auto-turrets and cannot attack air units. This makes them effective against small numbers of small ground units.

Covert-ops
Ravens can upgrade their auto-turrets to railgun turrets by equipping the Magrail Munitions upgrade.

Co-op Missions
Nova's SCVs can build railgun turrets at mineral cost. These turrets can be salvaged. Ravens innately construct railgun turrets instead of normal auto-turrets.
