maybe I did not make myself clear. Combat Experience is not limited to where and what you learn but also how do you know.
Maybe I should first started using an extreme example, and then ease off so you will understand.
Every Country have doctor, surgeon and physician, but does that mean we all know the same amount of Human anatomy? No. Can data study from human? Of course, but the truth behind it is very, very, far from you perform actual experiment on human.
If you have read anything about Unit 731 experiment, tho they are immoral, their study is invaluable to the combat science. How human react with any type of trauma, virus and Biological/Chemical attack. Those data you cannot get until you actually did those kind of stuff to your fellow human. I am not condoning the action of Unit 731, but their work actually did benefit those who hold that data. It does not matter if those data are 70 years ago, the human composite never change, that mean the same data can be applied today. Which give the edge of US, Japan and Allied Nation for its value.
So, is that same experience with CBG warfare is discounted today? You may think, yeah those experience are 70 years old and they have been thoroughly distributed between each nation, and we don't use prop plane anymore or we don't need airborne torpedo anymore. But the basis of conflict is still the same, there you are, you have an overwhelming force engaging a static islands, and a carrier force that supplement the island as an auxiliary force, this same situation can be happen all over again today, instead of diesel powered aircraft carrier, you have nuclear power aircraft carrier, instead of Torpedo plane, you have your jet striker, the hardware may be different, but the situation is the same.
Combat experience build on your loss. There are an old saying that you learn nothing until people start dying (for real.) We learn from carrier we lost and planes that re lost. Each fighter we lost in combat, each carrier we lost in combat is an hard earned experience, be that a far away carrier fight or a fire onboard a carrier like the 1967 Forrestal fire, you will not have the same experience and expertise to deal with the same situation unless you have a jet that accidentally shoot a rocket and ignite a fire on the aft of your carrier.
Do you know why we still study D-Day, Brécourt Manor Assault, Battle of Kurst, or even Battle of Hasting in West Point?? Even tho they are centuries or even millennium old battle??
