Armored formations are good analogy when you compare then in desert war, where the flank is open almost by definition(for example, North Africa 1940-43). Model Taiwan scenario still involves theater several thousand kilometers long, in either direction - long and deep.
PCA isn't armored cavalry, it's an elite raiding force. You can use it at frontlines - and there their stealth and speed will matter to little, as they'll be just another unit along, with many useless training and skills.
It's quite natural for high speed/vlo asset to get to work during initial stage, killing the whole system that supports bluefor's forward action.
Attack aircraft in transfer (CCA or manned fighters), attack damaged strandlers and SAR, attack support nodes(tankers, patrol/drones, aew/ew), attack transport aircraft, attack supply ships.
Typical interdiction.
