Flak cannon (Red Alert 2)

The Flak cannon is a Soviet Defence structure that is available under the 'Shield' tab, when building.

The Flak cannon is capable of looking at any angle (provided that angle is toward the sky) and rotates to track airborne targets, firing to deal moderate damage to the target. Flak cannons work best in groups, and do little damage on their own

Similar varieties of the Flak cannon are the Flak Track and the Flak Trooper
