22. Black Knight Unmanned Combat Vehicle
Talking about little machines that do the work without the need of assistance, this smaller tank is called ‘Black Knight Unmanned Combat Vehicle’ and it has so much firepower that it matches a normal sized tank! It has a 30mm cannon and 7.62mm coaxial machine gun, and it can be deployed from an aircraft. Just like MAARS, the Black Knight goes into high-risk mission to avoid the loss of human lives.
It still needs a lot of tweaks to the GPS, sensors and wireless communication though.
