Just throwing this out as a possible rule variant/house rule for various A&A games.
Currently AA guns are immune to attack, they are also limitted in terms of defensive ability.
Remove both restrictions by allowing a special type of attack… an Air Defense Raid.
Attacker uses a combined FIG/BOM attack force.
Defender may use AA AND FIGs in the attacked territory.
Attacking FIGs may only attack defending FIGs
Attacking BOMs may only attack AA guns
Defending FIGs may fire on FIGs and BOM (Attacker chooses OOL as normal)
The AA gun would fire at ALL incoming aircraft (as normal).
Then combat would continue with FIG on FIG and BOM on AA, with the AA gun getting to fire ON THE BOMBER(s) every round until destroyed or all the bombers were dead.
Only other rule modification… allow multiple AA guns to be in single territory, but 2nd (or more) guns could ONLY fire against bombers AFTER the opening fire shot in an Air Defense Raid.
Thoughts?
