Well it's a personal ranking based on personal opinion alone.

I wouldn't care much or take it seriously. That specific youtube guys has been videoing various types of military machine ranking.

As for me the world's greatest tank is the think tank.
Honestly one should never put too much pride on military equipment or machines. Strategy, training and skills as well as motives play a major part in winning any war not just what kind of tank one drives into battle.

Realization must be made that it is ALWAYS easier to destroy than to build and when applied to tanking the arsenal and weaponry to destroy a sophisticated tank are so numerous, effective, much cheaper and widely spread & deployed that in a full scale war a tank crew is not expected to survive that long in his tank. No matter what people say there's no one invincible tank.

a Crewless tank perhaps holds the most advantage in terms of operational survivability in a battlefield environment imo just that none is deployed.

Then again the world is yet to have seen another full scale war since the Korean and Vietnam war. Iraq's first war wouldn't fit a full scale war to me. Iraqis were fighting with pretty much obsolete equipment and inferior numbers especially in the air.

The Soviet tanks are often mistaken for being very much inferior when the fact is that they were designed according to a different doctrine than the West relied on.
Soviet designed tanks are designed to be deployed in superior numbers to overwhelm Western Europe defenses. Their strength lies primarily in their numbers while the West opted for superior more sophisticated tank building. The Soviet thought oh well even the superior Nazi tanks crumbled by the sheer weight of numbers of the simpler T-34s so why fix what aint broken.

I think someone mentioned that tank crews ride into battle so they could arrive first and die first too. A tank attracts too much attention and begs for immediate enemy response be it from the ground or air.
