No, it's the Airburst that makes it explode in the air.
Exploding in the well above the pilot the damage goes all for him. Just as it is possible to kill pilot with normal weapons.
For soldiers the damage of the ucav with Airburst is 100%, whether it is on the ground or in jets or helis.
Damage varies for each vehicle but does not destroy with vehicle 100 health. , so I can kill the pilot and gunner and the heli is still alive.
