Commander, you may be looking for the Nod Laser Turret.

The Laser Defense Turret was an advanced replacement for the Patriot Missile System developed for General Townes, who pioneered the use of deployable laser weapons in the US military. Like the Patriot, the Laser Defense Turret (LDT) could target ground and air targets within range, and relay the position of enemies to nearby turrets that might otherwise be out of range. However, the LDT's high-energy laser pulse was inescapable by enemy units and far more deadly than the Patriot's missiles. In particular, infantry and fast-moving units had no chance of getting out of the way. Suprisingly, during it's attack run, the Aurora Bomber seems to be invulnerable to the laser, but instantly becomes vulnerable the moment the payload is released.

Counters
Although not particularly expensive to construct, the LDT cost a lot in terms of base power resources. It was also as vulnerable as ever to long-range artillery units.
