The doctrine/task limits were capturing a reasonable average for the era, but it did a bad job for cases like the Harrier vs the Hornet, which perform similar missions but have drastically different max ranges. It also forced us into limiting CAS missions (even those flown by long range aircraft like the A-10) to 50nm since helicopters could commonly be fragged to them. This should allow us to design campaigns without needing airfields to be a max of ~50-100nm apart.
