Just yesterday there were at least two prolonged battles at A10. A CV came in and leveled the town while plenty of planes upped from the field and the CV killing each other over and over. LVTs began pouring in and now the fight shifts to having to defend air AND ground, and so supplies got run to the town to GF it, then the air fight resumed.
Both times it kept going and going and going until the CV was sunk.
So here you have one side using ship-based offensive weapons, aircraft, and LVTs... and it's somehow unfair that the town was resupped to focus on the air targets and not have to keep people low over the beach or town? If anything, those resupply runs kept the fight going longer. And it did that both times; kept the fight going on and on.
The attackers had plenty of heavy planes to keep the VH in check (mostly), and enough to run a few bombs and rockets into town now and then, but couldn't have one of them fly low from town to spawn looking for resuppliers? Hard to fathom.
Take away the ability to resupply and all you're going to get is easier base takes, so much easier that you won't get the fights you imagine but you will get people abandoning the base as lost and forming up to go where planes aren't to take a field of their own. It will be the same as the horde NOE mission days where even more combat avoidance will happen in the name of taking bases.
