Whining is cool, we all do it and sometimes it helps to make for a better set up, so feal free:)
"But can you enable some U.S. planes with some compatible firepower to the N1Ks in the CT? "
In terms of Just gun capabality's (not ordance carying capabality) the US planes are at in many ways an advantage over the Japanese planes. The 50 Cal out ranges all the japanese guns by a signastudmuffinant margine, it has for example 2 to 3 times the effective range of the Type 99 MK II cannons on the George. Most all the US planes cary a very large ammo load compared to the Japanese planes. All the US planes are very hard target's, while the Japanese ones are comparatively easy to kill with a good burst of 50 Call. So while the George has a slight advantage in True Hitting power per shell, this is not such a huge advantage for the above reasion's. Hsipanos are far more effective than the Cannons on the George, both in Hitting power effective range and in over all efectivenss aganst all types of targets, Ground, GV, ect, so coupled with the Huge ordance delevery advantage the US always has the C Hog would be over kill and is not neaded since the US realy has the Firpower (gun wise) advantage in this set up over all.
Their were Several George Units that particapated in the Okinawa Campagine, I can think of Three off hand ( but I am to lazy to pull out a book and look it up:) ), their were also several Ki 84, Ki 100 and Late model Ki 61 units at Okinawa as well, Obviously we dont have these planes in AH so we most make do with the George standing in for all of those (in most case's) better preforming planes. Not to hope on my soap box hear but The Japanese are also screwed in terms of their Atack planes The Kate and the Val were not being used in the front lines at this time of the war and since AH does not have the Jill,Juddy,Grace, Randy or Francis were forced to use 1930's planes in their stead, so again the Allies have it much better in this set than they would if we had those planes in AH, All of Which saw service over Okinawa (except maybe the Grace....).
