But it also does not justify sending in lightly armored vehicles like Strykers that will definitely not stand against even modest anti tank weaponry. Even dedicated light tanks are somewhat doubtful if the enemy can bring even second gen tanks to the fight like a T-72.
APS do not render anti tank missiles obsolete, they merely change the rules of engagement. Dummy warheads, faster and stronger missiles and volley launches are all possible counters to APS.
While it is true that the MBT is no longer the main deciding factor on the battlefield, it still has a role that no other armored vehicle can satisfactory fulfill, as an armored spearhead which can at least take a few hits and still carry on .
I won't say that the PLA is dumb in this regard, but rather they like the rest of the world has not yet figure out an alternative to the situation. Like it or not, we will still see MBT deployed in urban settings. The best the PLA can do would be to amply support them with infantry to screen their flanks where they can.
I think you're misunderstanding me. I don't condone light tanks being used this way or APS making missiles and rockets against tanks obsolete. But it does change the game and demand more from an enemy firing at the tank. That could be a very important difference. My real point is heavy tanks are just as dead as light tanks in these unfavourable scenarios and modern strategists will always avoid these urban settings if they can. PLA has more than enough choice to always avoid sending tanks in with zero support. There is literally no useful difference between a $2M Type 96b as it currently is, to a $3M upgraded Type 96 with reinforced side armour. Spending the half billion or so you save on drones and gunships alone will be enough to solve all your tank problems. Adding effective APS to this gen of tanks will upgrade them FAR more than adding any more layers of heavy armour.
