A note on choice A (Anzio).
To make it more closely match history, the estimated plane set is refined to the following:
Spitfire 9 [and maybe 8's -- tbd], P-47D-11, P-40 fighterbomber, B-26 vs. Bf 109G-6, FW 190A-5, and FW 190F-8 jabo.
If anyone wants to change his vote based on this adjustment, please feel free to do so.
