adeptitus, RoC have already assemble their own tank based on the M60 chasis. In fact, the CM11 and CM12 were the combination of such a vehicle. The chasis is based on the M60, while the turret is from the M48 with improved ballistic co mputer and fire control similar to the M60. Indeed, Israel tanks were able to manuver through Gaza, but this is Taiwan. Since you said they have been living in Taiwan, you would know that there are cars parking on the side of the street almost all the time. Sometimes, in smaller street, there are barely any room for even sedan to go through. WE're not talking about single tank, but a full Tank bridgades with his support units, alone with infantry, i think you really are left with small space. Also, if it come down to urban warefore, there are many tall buildings in Taiwan that are excellent spot for anti tank missiles to be fired from. I personally think the M60A3 is an excellent tank and is capable of defeating the amphibious forces. The PLA is less likely going to use Type 99 or 96 for beach landing. But, when the RoCA fail to stop the Chinese invasion, TAiwan is pretty much over, even if Taiwan have M1, they would be completed surrounded by PLA navy without supply and M1 would be fighting on empty gas tank.
