re: #73 William Lewis

Could fire the French ammo. Our more modern ammo was actually better. OTOH, locally made and easy to supply ammo, even if not as good, would trump better stuff shipped across the medium sized pond.

It’s funny to see the legacy of the US’s unpreparedness for WWI as reflected in our hasty purchase of so many French Canon de 75 modèle 1897 and it’s impact in the next war. Just for giggles, if I worked for a defense company I’d try sneaking in a spec for a IFV with a 75 that used those case dimensions…

Ah, from wiki…

The 75mm M2 and M3 tank guns of the M3 and M4 Medium tanks, the 75mm M6 tank gun of the M24 light tank and the 75mm gun of the -G and -H subtypes of the B-25 Mitchell bomber all used the same ammunition as the M1897. The 75mm Pack Howitzer M1 used the same projectiles fired from a smaller 75x272R case.
