accuracy as well as its capability to lock onto tanks. 21st century Performing situational awareness and communication is the one of four primary MBT functions in the 21st century. To improve the crew's situational awareness MBTs use circular review system with a combination of Augmented reality and Artificial Intelligence technologies. Further advancements in tank defense systems have led to the development of active protection systems. These involve either one of two options: Soft-kill – The Soft-kill protection systems use integrated on-board radar warning receivers which can detect incoming anti-tank missiles and projectiles. Once detected, soft-kill measures will be deployed which involves deploying smoke screens or smoke grenades which interfere with the incoming missile's infra-red tracking system. This will cause the incoming missile to miss the tank or to deactivate entirely Hard-kill – The more advanced approach involves the Hard-kill measures. These involve directly destroying the incoming enemy missile or projectile by deploying the tank's own anti-missile projectile. This is seen as a more reliable approach due to its direct intervention measures rather than interference measures of the soft-kill systems. Both these active protection systems can be found on several main battle tanks including the K2 Black Panther, the Merkava and the Leopard 2A7.
