Thank You Carl, I will try to leak in some interesting info related to the development of T-90.
For example the red eye look of this tank is caused by the Shtora-1 system, that is a electro-optical jammer designed to deal with the semiautomatic command to line of sight anti-tank missiles , laser based range finders etc.. Part of this system are two large IR reflectors, emitting coded, pulsed IR jamming when the guided missile is detected.
