Russia is sending their most modern next generation Tank.
T-14 Armata has a unmanned turret and the crew are in the front of the tank in a armored crew capsule. Its also equipped with active protection system, i.e a AESA radar to detect incoming rounds and then uses soft kill( laser,infrared dazler, smoke screen) or hard kill( fires of buck shot type canisters) to defeat the incoming projectile. It also turns the turret to the direction of the threat.
This tank formation is supported by BMPT terminator, this is repurposed T72 tank chassis equipped with twin 30mm gun and ATGMs, basically same firepower as a Attack helicopter. So far only one has been known to be destroyed by artillery. Otherwise this think packs a punch, hard to detect due to low profile and has modern Flir and night vision.
This
BMPT terminator was made from the lessons learned from Chechen urban war, where tanks suck due to poor vision, limited mobility and piss poor gun traverse.
Basically every tank nerd is waiting to see how these perform, since this will directly impact the future of AbramsX prototype tank, which was made in response to T14 Armata.
