Well i once promised a post in the Taiwan issue but it has fallen behind all other stuff...anyway my point in that topic would have been that PRC current Amph landing force and Airbrone units just aren't big and capaple enough to be able to do theyr task in the possiple Taiwan takeover.
This improvement need what Ute pointed out is exactly what i ment.
Soviets once chategorized amphibious landings in three category: First, small size tactical operations made by spetnazz units of the naval infantry, seccondly operational level landings wich were the highest that soviets themself could go and thirdly large strategic level landing operations wich only USMC was able. Soviets had usually two brigades per fleet (one was spetnazz brigade) in four fleets. Their naval infantry units where much larger than chinese current ones and still biggest task to them was opening bridge-ends to attack rear of advancing army units opponents. Taking over a large island whit twenty million people and significant army, USMC could hardly do it, not to mention soviets and most importantly the chinese naval infantry units.
Well China needs then boost its amphibious ship armanda and add more bigger landingships to effectively serve these 55,000 new marines.
Also, a battalion of Type 99 would be like 31-33 tanks, as chinese follows the holy trinity of Tsarist Russian unit cohesion, at least to my knowlidge. A regiment of 90+ tanks would be a minimium in my mind, thus dived in to all operational landing echelons or task groups of battalion size (the maxium unit size to be fileded whit LSD size ships sofar). Also the artillery must be up to date and ligth enough to be practical in fast pace missions.
But china still lacks true attack choppers, but i think this oncoming WZ-10 would be placed at least near major marine formations to be aviable in Taiwan landings (as it is the most potent next field for these marines to deploy)
But having dedicated airunits and so on would propaply require a semi-branch status among the Navy, air force and army, to avoid the byrocracy and staff proplems.
