Another post I agree with. By maintaining a strong ftr. force you can significantly delay a landing made by Allied Forces at both N. Africa or WE.
This forces UK and USA to work together as Allied transports can no longer move unprotected. Forcing money on building a Navy draws away IPCs much needed fronts and slows any build-up.
Ftrs. prove the perfect defense. If you’re defending with 6 inf. and 4 ftrs., the Allies are once again forced to build is higher numbers in order to overrun these defenses.
In all, ftrs. are the best way to slow down any sort of invasion.
