AR of Taiwan will be very interesting because of the 3 geographical features of the island, it affects doctrines on attacks, defense and falling back areas, and possible evacuation areas on the East coast for escape to Philippines or Japan.
The first and most important area is the West Coast lowland plains facing Fujian coasts. This is where PLA marines beach assaults and air borne troops insertions are expected at the initial phase of AR. This is the belt area for major population, agriculture, finance, manufacturing, power generation and highway network etc.
Another area of interest are the naval base and air bases on the pockets of lowland on the East coast like Hualien airbase and Su'ao port. PLA could either block off totally the East coast or leave an escape corridor here for tactical reason. Hualien airbase is the largest airbase on the island, and it is expected to be destroyed on the first minutes of the AR, so are the ships on Su'Ao navy base.
The 3rd area is the central mountain range where there might be a lot of radar sites and long range SAM sites. These sites are also to be the target of the Day 1 of AR. Mountains are natural fallback area for remnants of ROC forces once the coastal plains on both coasts have been taken over by PLA.
Problem for ROC remnants in mountain areas are fragile mountain roads that could easily be cut off by floods and landslides during storms or typhoon seasons or rocket/ bomb blasts. Movement of heavy equipment would be difficult and can be easily take out by PLA aerial sensors and strikes. Without logistic support, ROC remnants would have to resort to guerrilla warfare, but lacking ammo supplies, food, medical supplies, batteries and petrol, they will not last long.
Logistic, equipment and manpower numerical inferiority are the factors that ROC troops will be losing fast.
