Air Units

Air Units' stats and properties can be modified as a whole, by using the GameEnums.UnitType_Air variable.For instance:

CO_TEST.getOffensiveBonus = function (co, attacker, atkPosX, atkPosY,
    defender, defPosX, defPosY, isDefender, action,luckmode, map) {

    if (co.getIsCO0() === true) {
            switch (co.getPowerMode()) {

            case GameEnums.PowerMode_Power:
                if (attacker.getUnitType() === GameEnums.UnitType_Air) {
                    return 30;
                }
            break; 
       //rest of the code goes here
       }

    }

}

Increases the Offense of Air Units by 30% during the CO Power.

Modifying stats or properties of specific Units

Each Unit can be modified through a comparison of the UnitID. The Unit ID can be obtained through unit.getUnitID() And it's of a String type.

Possible values are:

Air Units
K_HELI	T_HELI	DUSTER	BOMBER	STEALTHBOMBER
TRANSPORTPLANE	FIGHTER	WATERPLANE	ZCOUNIT_KIROV

Of these, the ones with the ZCOUNIT_ prefix are Units specific to COs that cannot be deployed by the rest.
