The Super aEgis 2 is an automated gun tower that can find and lock on to a human-sized target in pitch darkness at a distance of up to 1.36 miles (2.2 kilometers). It uses a 35x zoom CCD camera with 'enhancement feature' for bad weather, in conjunction with a dual FOV, autofocus Infra-Red sensor, to pick out targets.
Then it brings the pain, either with a standard 12.7mm caliber machine-gun, a 40mm automatic grenade launcher upgrade, or whatever other weapons system you want to bolt on to it, including surface-to-air missiles. A laser range finder helps to calibrate aim, and a gyroscopic stabilizer unit helps correct both the video system's aim and the direction of the guns after recoil pushes them off-target.
Each 140 kg (308.6 lb.) unit can be rigidly mounted or put on a moving vehicle, where the gyro stabilization would be a huge asset. They can operate in fully autonomous mode, firing first and asking questions later, or they can be put into a manual mode for more human intervention. All machines communicate back to headquarters through a LAN cable or wireless network.
