In a combined arm operation the IFV act like battle field taxi they are there to transport infantry to protect tank from the opponent ATGM operator then they scud away.
That is how a combined arm operation work Tank is not going to operate alone they will be accompanied by soldier In the WWII there is no IFV because tank speed was relatively slow But modern tank are faster therefore the need for IFV.
But they are battle field taxi to transport infantry man with their portable ATGM that is why you have HJ12
HJ10 will operate at the back of the tank using optical guide to kill the opponent tank with longer range missile of 10km
Don't you think I'm perfectly aware of that? Tank operations are usually escorted by mechanized infantry whose job is to flush out anti-tank rockets in combination with artillery. In WW2, tanks were actually escorted by motorized or mechanized infantry to help screen against anti-tank guns.
Problem is, the most reliable way to kill a tank is another tank; the intrinsic deficiencies of anti-tank infantry is that they're squishy and short-ranged, the intrinsic deficiencies of anti-tank vehicles are that they tend to have very thin armor. Tanks, on the other hand, are both lethal, potentially long-ranged, and survivable. Think of it this way, if a tank platoon with support gets hit by a Time-On-Target attack, who survives? The tanks are usually well-armored enough to do so, barring some lucky direct hits. The IFVs, the infantry, etc, these get wrecked.
If you look at APS systems that kill tanks, the main issue is that APS can only cover so many missiles at once. Once the APS is saturated, the active defenses no longer work. But while APS can stop missiles rather effectively, the most modern APS have difficulty stopping 1500-2000 m/s projectiles shot out of a tank cannon. Moreover, it's easier to saturate a target with APFSDS than with missiles.

In either case, the ZTZ-96 was designed to kill T-72s, and it has the fire control advantage to do so. ZTZ-99 was designed to compete with Abrams, and it has the armor to be competitive. The ZTQ-15 isn't designed to kill either of these, as it's fundamentally a light tank for difficult terrain. But it'd be better if it had an option to do so, instead of having to rely on escorts.
