Air units and Interceptor promotion

[Thalassicus]

The interceptor promotion is not visible or otherwise available for selection when you promote an air unit within the game. The in-game civilopedia and external XML files indicate it's possible in information on the promotion itself, however, and unit cards as well in the civilopedia.

The expected behavior would be either:

1) Make it available
or
2) Remove the boldfaced lines below from CIV4PromotionsInfo under PROMOTION_INTERCEPTION1 and PROMOTION_INTERCEPTION2:

			<UnitCombats>
[B][I]				<UnitCombat>
					<UnitCombatType>UNITCOMBAT_AIR</UnitCombatType>
					<bUnitCombat>1</bUnitCombat>
				</UnitCombat>[/I][/B]
				<UnitCombat>
					<UnitCombatType>UNITCOMBAT_GUN</UnitCombatType>
					<bUnitCombat>1</bUnitCombat>
				</UnitCombat>
			</UnitCombats>

The purpose would be to increase interception chances against things that have bonuses against being intercepted - stealth bombers, cruise missiles, and nukes.

I have no idea if it would work if you enabled it though.

If your air unit is wounded, its intercept chance is reduced, and there is also the evasion promotion which would also counter the interception percentage.

Since fighters are so strong vs. bombers (almost 5/1 at full strength), it would be an advantage for even a damaged fighter to go against a bomber.

The thing is, you can't promote a fighter with Interceptor. Only Combat, Pinch, Ambush and Ace are available.

Last night I noticed that too. I think it's a bug.

Per Solver at Apolyton:
"That'd be because Fighters have 100% interception probability already, hence the promotion would be meaningless. If you, for example, changed Fighters to 70% interception chance, the promotion would re-enable itself."

A reply by myself:
"Sorry, I always thought the interception promotions for fighters were for use against air units with evasion (stealth bombers or units with the promotion). Also for when the fighters were damaged, so you could still have an improved chance of intercept, though burn the fighters out earlier."

and Solver again:
"Doesn't work like that. Evasion takes precedence over interception, and the promotion only modifies the base intercept chance, so it wouldn't do anything to damaged Fighters."

Sounds like the bug is #2 then.
