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, along with their weapon names:

Air units and their weapon strings

Air Units	Primary Weapon String	Secondary Weapon String
K_HELI	WEAPON_AIR_TO_GROUND_MISSILE	WEAPON_K_HELI_MG
T_HELI	N/A	N/A
DUSTER	WEAPON_AIRPLANE_MG	N/A
BOMBER	WEAPON_BOMB	N/A
STEALTHBOMBER	WEAPON_STEALTHROCKET	N/A
TRANSPORTPLANE	N/A	N/A
FIGHTER	WEAPON_AIR_TO_AIR_MISSILE	N/A
WATERPLANE	N/A
ZCOUNIT_KIROV	N/A
BLACK_BOMB	N/A

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