Helicopter Co-Pilot Gun Turret Folder Location
We must first locate the folder location of the Co-Pilot Gun Turret. This is different from all of the other weapons, because it is actually within the helicopter's code.

1. Navigate to C:/BF2_Directory/mods/bf2/.
2. Open Objects_Server.zip.
3. Open Vehicles/Air/.

Helicopter Names
Each Helicopter has its own Co-Pilot Gun Turret. The Attack Helicopters names are shown below:

ahe_ah1z
ahe_havoc
ahe_z10

Explosion Damage
First, we will begin by modifying the Explosion Damage of the Co-Pilot Gun Turret.

1. Open the ahe_ah1z folder.
2. Open ahe_ah1z.tweak with Notepad.
3. CTRL + F and type "ObjectTemplate.detonation.explosionDamage 75".
4. Change the number (75) after explosionDamage to a number of your choice (do NOT exceed 3000).

Explosion Radius
Next, we will modify the Explosion Radius of the Co-Pilot Gun Turret.

5. CTRL + F and type "ObjectTemplate.detonation.explosionRadius 3".
6. Change the number (3) after explosionRadius to a number of your choice.

Explosion Force
We will now modify the Explosion Force of the Co-Pilot Gun Turret. This is what causes even more damage if a high number.

7. CTRL + F and type "ObjectTemplate.detonation.explosionForce 2.5".
8. Change the number (2.5) after explosionForce to a number of your choice.

Damage
Although we have modified the Explosion Damage, we must modify the Damage. This is actually the damage that is added into the equation for damaging a player.

9. CTRL + F and type "ObjectTemplate.damage 20".
10. Change the number (20) after damage to a number of your choice (do NOT exceed 3000).
