Tanks are obsolete technology today

It is good that the West are moving some tanks into Ukraine. Tanks are expensive to keep up, they are hugely contaminating the environment. Main thing is, that already the Azerbaijani - Armenian war showed that tanks are easily destroyed by cheap Turkish drones (hey, Bayraktar, how are you doing today?) U.S. marines left behind their tanks long time ago. Smart decision. Tank these days is an expensive polluting trap for the persons, who are sitting inside.
