Quad cannon with automatic aiming system have some chances to destroy jets flying at low altitude.
In real life quad cannon have no hope of shooting down an air craft made after 1950,
Nowdays they are developing new type of missile for Patriot that will be able to destroy ground targets. Possibly it is further development of ADATS project.
Patriot missle launchers DO NOT attack tanks, or even planes, EVER ,
TOS-2 and TOS-3 are under development already. As TOS-1, they will be heavy flame thrwing systems equipped with thermobarical or incendiary warheads. Of course, anti ground only. Their names are known, but regrettably there is no any other data (top secret)
but I could also just call it a TOS II or III and do what ever I want
I simply don't want somebody to distort reality very much. If you want an anti aircraft flamethrower then think up it, model it and give it a fantastic name. Of course, you can use Buratino too, but at first, let it be anti ground only like in reality. At second, it is Russian unit. Why must it be Chinese in game? Let China to have its own original flamethrowers.
Or, if TOS realy offends you I could just call it missle tanki/site.
Why do not to think up your own launcher? To say, PMS-4A (Pendaelose Missile System modification №4, A = advanced)
If a patriot can be abused... so can a TOS, or we can rename it. In real life there are very few missle launchers that attack everything the way a launcher will in game.
