The Japanese side should adopt their indigenous Type 4 75mm anti-aircraft gun(四式七糎半高射砲) instead of the German PaK 40.

The US anti-aircraft guns should be the 40mm Bofors (4-round clip) or the towed water-cooled 12.7mm M2 machine gun (200-round belt).

Italy should adopt the Breda 20/65 M35 instead of the German Flak 38.
