Air units-> no use armorpiercing ammo.

[DRG]

Becasue on aircraft, and aircraft only, the ONLY slot used for weapons is the HE number. The AP number is used to indicate the number of guns firing that weapon therefore it cannot be used to indicate AP ammo

This is basic Steel Panthers stuff. It's been done that way since SP1 was developed

Class 11 air weapons if auto cannon or MG will use the HE ammo number for number of engagement opportunities, and the AP byte is then used to represent the number of cannons/MGs for this type of class 11 weapon. Helicopters use normal on-map MG or cannon classes, not class 11. You may therefore need a copy of say a 12.7 gatling - one off map for fixed wing planes and one on map, with normal AP ammo and possibly sabot for your helicopters to use.
