Don’t worry about trolling, if your a military professional as the site says you are, and participating in war games, the smart users will heed your words.
So the first thing will have to be is not attack any outside power, at least not on Taiwan itself. It’s also the only way for China to avoid the U.S. justifying the full deployment against China, especially assets on the mainland.
You can't just stay put tho.
US will eventually help Taiwan one way or another, either by directly involved (ie sending troop) or indirectly involved like what the US did to Ukraine, the reason I attacked is because it's pointless if the US Flagged ship cannot be attacked bringing in supplies (That's what they do in Day 1), it's going to be the same, we might as well fight the US out. That way it buy me some time.
At least with the missile strike, I can take out some infrastructure, what I did not put into my calculation is that the US fleet leave port before D-Day. Now I need to find them and hunt them down, I have already traded Fijian for JS Izumo (Through it was USS America) I am now down to 2 Carrier and a bunch of Destroyer that got tied down by the antisub and beachhead security operation. I don't have enough ship to challenge anything outside of my missile range, yet.
An “exclusion zone” as in the falklands war will probably be the next step declared by China, just within the Chinese/Taiwanese exclusion zone. Operating from here, the assets could try to maintain ISTAR support, and detect intrusions by the CTF. Could China put 3-4 Type 003 class PLAN carrier battle groups as some Type 076 light carrier based carrier battle groups with stealth drones east of Taiwan to be able to detect and try to drive off these unknown aircraft (are you currently limited by systems that currently operational in China and the US?). Remember Subic Bay is being deactivated, so that will be another axis of attack to keep an eye on.
Well, the problem is for China, I will have to defend Northern, Eastern and Southern Approach.
I can't split my force into 3 different AO while trying to secure my side of the ocean. I need to screen US, Japanese and Taiwanese sub off my invasion force, both North and South, that's 20 destroyer and 2 AC there. Then I have P8i and P-3i flew from Japan and Guam and I suspected Darwin, Australia (Can't be sure) which mean I can't punch thru my sub until I have Air Superiority over those area, which is hard to contest with ground base SAM + a mix of F-22 and F-35. Right now, I can shoot down any incoming US/Japan/Taiwanese fighter, but if I change the spec and move out of my Combine Task Force area, I will lose both SAM and Ballistic Support, my Navy will be on their own, which I think that is going to end up badly.
Missile systems will have get longer ranges to keep them under the defense of the IADS.
I put my missile system around 20km inside Chinese Coast, and using the AWACS to patrol the gap between the edge of the range and the missile system, and then I can't move my missile until I make progress inland. This is what got me stuck at the moment. I can't move my ship because I need them to stay in the west coast to support the beachhead. And I am currently contesting the American over the Air Superiority. And I suspect when the US started to lose or have their stock grind down, they will pull other alliance in.
At this point, I have my ground troop posted near North Korean border in case the Japanese invade/counter attack from there, or for US to drag South Korean into the game. I also posted considerable amount of troop in VIetnam and Indian border in case both country try anything while I am taking on Taiwan. So my entire force is splited, and I am not really willing to draw force from any of the aforementioned AO to Taiwan.
Can you replenish your troop numbers with Helicopters, now that you have a secure beachhead? Also the population centers are on the coastal plains. Are there places in the interior, in mountainous areas but near the next target city Keelung, that you could secure to open new axis of attack?
Not when the Taiwanese keep counter attacking. Resistance is high and I lost an entire regiment from taking Keelung. My original plan was to land 6 Regiments in the North and South, trying to draw as much force away from each other so they cannot mutually support each other, I also send 1 regiment to Penghu and a single battalion to take Matsu. My plan was, once my landing draws off the Taiwanese force, splitting them North and South, I would land another 4 Regiments somewhere in between and link up both beachhead and put the pressure in the Taiwanese/American line. but At this point, most of that 3rd landing force I have I've been using them to replace the loss I have in both beachhead. I need a standalone force to punch another hole somewhere down the line and I am waging the force, but it takes times to form it and transport it, it will take up to 90 days for my estimation.
