Like how did they film what the Chinese were doing during that time?
Engagements, even near engagements are recorded over layers of logs and warfare systems. They are recorded, debriefed, and lessons learned are garnered from them. New lessons are considered against current doctrines. And so forth.
That video was probably pieced together from unrelated events. The vid is just provided to carry the events in that order of battle the vid maker received from whatever source.
That vid maker slanted things from the US angle. There are vids slanted by foreign angles too. Search some chinese sympathy shit and youtube will feed them to you.
Chinese are not in our class in deep water. Their threat is even if we sink their ships 10 to 1 they can outproduce us in replacements. But this administration has moved to start fixing that.
