This sort of stuff probably better worked out by email or PM feel free to do either esp if looking at releasing as a scenerio.
On Chinese planes the idea of remains arriving piecemeal is good if there were actually any left, they would have probably tried stopping the fleet or hitting landings.
SAMs as objectives therefore a good idea perhaps give Chinese helos rather than fast air as reinforcements & used in landings, still piecemeal arrival & transports could be loaded . Marine Mech formation light tanks & or MBT could also turn up as reinforcements in a more organised maner, assuming taken the ground but not had time to consolidate positions before USMC turn up.
