Hunter-Killer Capability
The KCPS not only features sights for the tank commander, but for the gunner as well. The gunner has an entirely separate sight, the KGPS, available for use while being able to rapidly switch over to which target the commander is looking at by using the alternate optics available for the gunner on the KCPS, which the gunner can also control by zooming the image in and out. This allows the vehicle to engage in effective hunter-killer tactics, where the gunner will engage a target while the commander picks out another target for the gunner to engage next, reducing the time required for target-acquisition. The KCPS-equipped K1A1 were found to be having an upper-hand over the U.S. Army's M1A1 Abrams, which do not have hunter-killer capability, during training exercises where the two types of tanks were pitted against each other.
