Tanks are sitting ducks in modern warfare.
New Western ones are 10 million usd each
Obese 70 ton heaps of steel
Sink through bridges and overpasses. Also way too heavy for soft terrain.
Need endless amounts of fuel
Difficult to repair
3 or 4 man crew
Lots of maintenance
Problematic to transport (Ukrainian tank transporters were built for lighter weight Russian tanks. The Obese Western ones destroyed the transporters).
Long ago tanks without air cover were an expensive way of suicide. Now tanks without total drone protection are a very expensive way of suicide.
Most vulnerable part of any main battle tank are the tracks. Hit one of the track with a 1500 usd RPG and it's game over for the Main Battle Tank. Crew gets out, and then it is a matter of time before cheap artillery hits it.
Even the most advanced tanks in the world cannot deal with a 1960s mine. Does not even need to be a heavy anti tank mine. As long as one of the tracks is ripped off the tank becomes a sitting duck.
