Never, but never deploy tanks in an urban environment where there are tall buildings.
Really. Tanks in an urban environment. Isn’t that chapter one in the infantry manual? It’s Christmas and Easter rolled into one if you can lure the enemy into it.
Your 58 ton multi million dollar investment becomes a human barbecue for anyone with a bottle of gas and a match.
In general, very good advice. But there are exceptions-- given that you have experienced supporting infantry and effective TTPs and situational awareness. There are times when the lethality of the tank is useful for obstacle/strongpoint reduction-- if infantry can clear/secure the path to a firing position, then moving the tank up to do the deed and then scoot is fine. Also situations where the tank operates more closely with infantry against numerically superior dismounts with limited/no AT capability-- with the right TTPs and experience the enhanced lethality can make quick work of what would otherwise be a serious PITA.
