Except what happened is Active Protection Systems, which are currently tipping the balance back towards the tank. NATO ignored APS for years, but recent events in Syria have NATO scrambling to bolt APS onto our tanks while Russia and Israel laugh and say “I told you so.”
APS is great technology. But Trophy costs nearly $1 million per tank. You can buy a lot of missiles for the cost of outfitting just one company of tanks with those.
At some point, the cost of protecting the tank outweighs the benefit of having it in the field at all.
