The beam cannon is a Nod anti-vehicle defense in Tiberium Alliances.
It is a very powerful structure effective for taking out attacking vehicles. It's possible that this could be the emplacement version of the Beam cannon vehicle.
The beam cannon can be upgraded with Stealth: it cannot be attacked unless it attacks first.
|Defense is cloaked and cannot be attacked unless it attacks first. Interrupted by vehicles within range. Cannot re-enter stealth.
