I personally do not believe that Normandy is an appropriate analogy to an invasion by the PLA on Taiwan. The reason is that Taiwan doesn't have the strategic depth Nazi German had at the time, also, you're discounting the greatly decreased reaction time of both sides due to advances in technology. Such a change would favor numerical superiority. You can argue that the Taiwanese C4I is superior, but there are two problems
1) Taiwan's military exercises have uncovered some serious flows in C2 capabilities
2) The supposed advance of Taiwanese C4I structure does not outweigh Chinese numerical advantage
