Tanks are deathtraps in cities. Attackers trap them with obstacles and then attack with RPGs. See the footage on YouTube in Chechnya or Syria.
In the open battlefield as in Iraq 1 (especially) and 2 they were very effective although of course airpower is the key factor.

That was artillery and aircraft's, mostly NOT Tank VS Tank.

To quote from this book, about regarding how badly they faired in Chechnya (as mentioned above):
> High casualties, massive collateral damage, and heavy losses in vehicles and equipment all point to the apparent folly of using tanks in the urban fight. This chapter will discuss the 1995 battle for Grozny and examine why the Russian armor did not achieve the desired results.
So... the argument is that "Russians don't know how to use tanks". I don't find this argument particularly persuasive.
It's true that up-armourmed Abrams in Fallujah proved effective against RPG-7s (as mentioned in your link). But the RPG-29 was used in Syria successfully against them, and (more often) by Hezbollah against the Merkava tanks.

Tanks are not used for that anymore, they are used as little fortresses in cities, but fighting on a open field..well you have seen what happened in the first and second iraq war.
