Ok Ok ive got it,
when all fuel bunks are destroyed, allow either 5 more fighters to up with no more than 25%, or 2 bombers@ 25%
that would simulate the realistic "running out" of gas insted of just instantly it bing gone, after all, who wouldent be smart enough to have a few barrels stashed away?

But as-is, attackaing fuel bunks (and ammo but we'll burn that bridge later) is useless bucaues when a base is under attack the fighters are going to have 1 mission, defend it. and %25 fuel is WAAAYY plenty to accomplish that, plus IMO the fuel bunks make better and more interesting targets than the hangers.
AS for ammo, why not when all ammo is gone
A: disable ord (done)
B: restrick fighters ammount of ammo load to:
if 1 bunk is left half usual load.
if none are left 1/4 usual load.
again for the same reasons as fuel. all taking out the ammo does is disable ord, which is useless to do since the fighters that are going to be taking off to get ya will not be wanting to carry any.
