Performing situational awareness and communication is the one of four primary MBT functions in the 21st century.<ref name=MBT>{{cite web | last = Slyusar | first = Vadym | title = Methodology of identification of the critical requirements for armaments and military equipment.| work = VI International Scientific and Practical Conference "Coordination problems of military technical and devensive industrial policy in Ukraine.

To improve the crew's situational awareness MBTs use [[circular review system]] with a combination of [[Augmented reality]] and [[Artificial Intelligence]] technologies.<ref name=AI>{{cite web | last = Slyusar | first = Vadym | title = Artificial intelligence as the basis of future control networks.  | work = Preprint | date = 2019 |url=https://www.researchgate.net/publication/334573170}}</ref>

Further advancements in tank defense systems have led to the development of [[active protection system]]s, which may be classified as either:

* '''Soft-kill''' – Soft-kill protection systems use integrated on-board [[radar warning receiver]]s which can detect incoming anti-tank missiles and projectiles. Once detected, measures such as [[smoke screen]]s or [[smoke grenade]]s are deployed, interfering with the incoming missile's tracking system, causing it to miss the tank or to deactivate.
* '''Hard-kill''' – The more advanced approach involves destroying the incoming enemy missile or projectile by deploying anti-missile projectiles. This is seen more reliable protection.

Both these active protection systems can be found on several [[main battle tank]]s including the [[K2 Black Panther]], the Merkava and the Leopard 2A7.
