Below is a small description about the AHOI-Treasure Air units.
(I want to mention that this design also had in mind that it’s possible to maybe add later an earlier timeline as WWII.)
The famous ones from early WW1 bombing missions.
There have been test from USA to have some sort of flying Aircraft Carrier for long range naval patrol in the late 20’ies. But I’m afraid the engine will not allow us to have such in the game..
The basic fighter planes from WW1 to WW2.. Not specialized.
Fighter-Bomber version of planes like Me-109, FW-190, Hawker Hurricane, P-47..
Interceptor are the special Fighter planes especially designed to intercept bomber planes like eg. TA-152 or other high altitude piston fighters.
The twin engine heavy planes like BF110, Mosquito, P-38 etc..
Close Air Support:
All those special CAS-types like Ju-87, Iljuschin Il-2 etc..
All those planes wich were used in naval bomber role. Starting from Catalina up to FW-200 to the late navy patrol bombers like Consolidated PB4Y-2 Privateer.

(See also the description about Aircraft Carrier in the naval units section.)
All those single engine bombers that were used by some nations like Fairey Battle.
All those 2-engine Bombers like He111, Ilyushin Il-4, Mitsubishi G4M, North American B-25 Mitchell..
