There was also the whole non-co-operation-over-weapons-development thing too. Factories had to make two copies of the same weapon but chambered for slightly different sized cartridges in some cases, and heaven forbid a Zero got Ho-5 instead of Type-99 20mm cannons for it's wings (which happened, and vice versa with Army fighters like the Hien)....it would have to rely entire on it's crappy 7.62mm machine guns because it wouldn't be able to load any cannon ammo at all.
