Tanks getting hit by 300 m range RPGs is tactically a failure of the supporting Infantry which is responsible for denying enemy anti tank teams a tactically superior firing position.
WOT is like any other war. Casualties of not only tanks, but Infantry and other arms also occurred.
Casualties are part of war. Though not completely avoidable, but they can be minimized by superior tactics.
Effective range of RPG against static targets is 300 m. If an enemy RPG team manages to reach within 300 m of a tank, then either the enemy anti tank team or the tank deserves to be roasted.
It's a failure of tactics, not the equipment.
We were going through a learning phase at that time.
You can judge this from the fact that.... When was the last time you even heard that we lost a tank to terrorists.
These older tanks, however, still possess some characteristics which even the latest tanks don't have even now....... Simplicity, maintenance and ease of operating being the first.
