Intersting point. I was thinking that the only reason to have truck based missles is to have a second-strike capability. Their mobility allows them to live through a Chinese first strike. Quite a few launcher based missles would also probably survive, but they could be used to hit apartment blocks in Nanjing or whatever before they were knocked out. If you want to use them against the most vunerable Chinese targets in all of the possible war, the ships of the invasion fleet and the beachead, they would have to be survivable. Thus the mobility of a truck launcher or the armour of a hardened launcher. I was thinking from a military point of view. Through my thinking, I would not fire any missles at the mainland, because their effect would be minimal annd their chance of success relatively small, except for at high value targets like a bunch of Zubyrs at dock. I would fire them at ships and beachead targets, where the Chinese would be most vunerable and the effect of the missles would be greatest.
You would fire at mainland targets, including civillian ones, to try to show the PRC that it is in a real war, where people die, including its own civillians. You also would fire at military targets to try to do the same to the PRC that it could do to Taiwan.
I think a prudent commander would go with a mix of both, saving as many missles as possible for the actual invasion but firing enough at the mainland for propaganda purposes.
