Eldar - Heavy Support
Whilst the Cobra is a potent weapon in its own right, its primary role is as a war engine hunter. Its distort cannon is capable of destroying a super heavy tank or small Imperial Titan with a single shot. From the Forgeworld Displays.
Another design of the Eldar Cobra.
The Cobra is another of the Eldar's Engines of Vaul, much like the Scorpion, but re-armed with a massive D-cannon. This is a weapon capable of tearing a hole through time and space, and allowing the Immaterium to flood into the material plane with terrible destructive force.
