The Photon Cannon is the primary defensive structure for the Protoss. Its ability to hit both air and ground targets makes it a strong deterrant against any enemy attack. The Photon Cannon also serves as a detector against any cloaked enemy units. These attributes combine to make the Photon Cannon one of the best overall defensive structures found in StarCraft.
