A supposed military operation by China against Taiwan has to be very well thought out.
We need to address Taiwan's military power, especially its level of preparedness and readiness. From an amphibious operations planner's perspective, Taiwan is not a particularly attractive target. While it is certainly true that the most notable amphibious attacks such as Normandy and Inchon have stunned their enemies against unlikely targets, there are limits to the possibilities of overcoming physical obstacles for a successful attack.
Taiwan's eastern side is mountainous and offers very few operational maneuvering opportunities for tanks without the support of engineering weapons, weapons that need constant protection to operate. Access to much of Taiwan's west side is blocked by muddy plains that stretch many kilometers off the coast, and to a country that has more than 200 Patriot PAC-3 launchers (15 batteries) and a dozen more Sky Bow II and III an air strike becomes expensive. An attack against the far north of the island in the Taipei area would quickly turn into urban terrain operations of a type that would likely not produce decisive results quickly, no wonder the Taiwanese army has so many ATGMs and attack helicopters. Similar difficulties would arise with attacks in the southern area between Tainan and Kao-hsiung.
By the process of elimination, the most attractive [though not the most likely] target for an amphibious attack on Taiwan would be the coastal region between Tung-Hsiao and San-Wan. Midway between Taipei's northern urban agglomeration and the centrally populated region around Taichung, this coastal area is free of irritating mud flats and offers open terrain suitable for the construction of a beach head and subsequent decisive manoeuvring. An accommodation in this area would cut the island in half and lay the foundations for subsequent operations in the north and south.
But the same area is heavily protected by Taiwan, protected to the point that any local incursions are costly in terms of human and material lives. Do not think that carrying out military operations with a wide margin for large human losses is easily possible, especially without the proper war doctrine for this, which I believe only the US has, since Chinese doctrine does not use the MBT T-96 as a means. landing. Attentive to the operations in the Pacific islands of the 2nd GM, where there was no alternative, the USA planned to be able to land even on organized and defended beaches, in the immediate vicinity of the target to be conquered. The symbol of this theory is the AAV-7 amphibious vehicle: an armored craft designed to transport infantry ashore under intense direct and indirect enemy fire, landed with cavalry support from the Marines' M1A2. The Russian school of amphibious warfare (which the Chinese is inspired by), on the other hand, intends to land on remote and unorganized beaches for defense, even far from the target, to be later reached by land. It's no coincidence that the Russians don't use CCs and crawler transport vehicles like the AAV7, but operate amphibious tanks, which despite being good, are far inferior to Taiwan's traditional CCs in terms of armor, their means of landing (Russians ) are also the helicopter, speedboats and BTRs.
Taiwan is made up of a great natural defense and the rest of rough terrain, excellent for defenders and terrible for attackers. Couple that with reasonable FAs, and the result is a nightmare for any attacker, even the PLA. I don't know of a country that, during the cold war, dug into mountains to set up air bases in the middle of the jungle and mountains.
Therefore, Taiwan was never synonymous with lack of preparation or fragility, quite the opposite. There is a PDF of a Chinese military man residing in Bern, who explained that at the height of the mobilization, Taiwan had 2 million heavily armed men ready for war, or in reserve waiting, today they have 1.6 million, which represents almost 7% of the total population.
Chinese generals studied various plans to invade Taiwan. All of them were extremely concerned about the strength of the army and its AAW defense, as well as the ability of the Taiwanese to make a very high price for this invasion.
In that case, all PLA infantry will be subjected to merciless heavy fire from Taiwanese artillery hidden in the jungle-covered mountains, or else the PLAAF will be subjected to massive AAe artillery fire. It's suicide to think about it without a 5th generation vector. Taiwanese forces may hold out for a long time in the local jungle, or long enough to make an operation unthinkable. It's not about winning, it's about being deterrent, they don't need to be superior but deterrent. These Chinese invasion plans recognize that the Taiwanese in reserve are reasonable marksmen, and for that very reason, they recommended using considerable and numerous forces for the attack.
Any Chinese occupation of parts of "Island Formosa" would cost a lot of blood. If the Chinese war machine can invade and conquer Taiwan?
I believe so, but with a few hundred thousand casualties to pay the price. But remember, planes don't occupy territory, you have to put “boots on the ground”. And then, an asymmetric war would make the PLA bleed for every inch of land, every stone, every bush and every corner. And that would make the cost of a military undertaking too high for such a small benefit.
If Taiwan has several bases hidden in the middle of the mountains and jungles, and the worst, the anti-aircraft systems are many aeromobiles, especially the AAW systems produced in Taiwan, which are mounted on light trucks with easy mobility like the Sky Sword II (TC- 2), and dozens of CS/MPQ-90 Bee Eye radars. In addition to Taiwan's anti-aircraft warfare doctrine, it favors the use of its AAW systems in areas covered with dense vegetation, where even drone sensors cannot detect systems below the glass of the trees.
The point was never to win, but to impose heavy losses. The Serbs' mistake was that they had too few anti-aircraft systems, which Taiwan has far too many. There is no detection without the use of airborne early warning aircraft in such a situation, as there are many targets to be detected at the same time and constantly, drones only do the work of supporting and attacking small platoons and brigades, as they have a detection limit of quantity targets and generally act against poorly fortified targets as occurred in Karabah, otherwise the Chinese will have to send thousands of drones. These are non-stealth drones that would be detected by various anti-aircraft systems in Taiwan. You should also know that the Taiwan Army has more than 2,000 Stingers in operation, plus 150 systems between MIM-72/M48 Chaparral and AN/TWQ-1 Avenger, which is hell for any surveillance drone, which would oblige the vectors operating at very high altitudes, greatly affecting their surveillance capacity.
In addition to the war doctrine, use a large part of its anti-naval artillery entrenched in dense areas of jungle and close to mangroves. Not to mention the infrastructures developed for war, such as trails, bridges and tunnels created during the cold war to use artillery in case of war. If the few skillful points for a landing would be saturated, why not hide the various artillery systems in the dense jungle of the jungle, in an infrastructure already created for that?
