I saw another program on Gettysburg. I think it was about apply Sun Tzu to battle philosopies. From what I remember, the Confederates original goal was a suppply depot near Harrisburg. For some ereason one of the Confederate generals or leaders what a new pair of boots. So, that part of the confederate army went to Gettysburg. Once there Lee kept trying to take the hill instead of just going around. So they got slaughtered. I'm not as well versed in the Civil war though.

As for the Me/Bf-109, it was essentially a pivatol design. It actually served in the Spanish Civil war. Its nemisis there was the Russian I-16. The I-16 was also a pivotal design as all metal and retractable landing gear. The Military Channel did include the Spitfire. Ithink they should have done a split, like they did on the F-86, Mig 15. Still, I'd give a nod to the Me-109. Also, the Camel might have some competition from the Dr-7.
I also disagree with the selection of bombers. I think the B-17 and / B-24 should be rated higher. If not #1. Although I think the contribution of Brittish bombers are probably underrated.
As for the rifles, the Mauser m-98 should be rated a lot higher. The SMLE rated righer than the M-98. I don't think so.
I do see some slant towards an American and Allied selection. In sports, there was a selection of 100 greatest atheletes. I don't even remember Pele making the list. Even American kids knew who he was. I'd rate him up there with Micheal Jordan, Ali, and a few others who had global recognition. He was a phanominal athele. I think 10.6 in the 100 meters, 6 ft vertical jump and could see 270 degree.
