During the arming phase, equip your Apache helicopter with radar-guided
AGM-114L Hellfire missiles instead of the laser-guided AGM-114K Hellfire
II. The AGM-114L missile is specifically designed for Lock On After Launch
(LOAL) capabilities, which will enable you to fire at ground units from
behind cover without exposing the aircraft to enemy fire.
Destroying air units
If you run out of air-to-air missiles, other weapons, such as chain
guns and guided missiles, can be used against both fixed-wing and
rotary aircraft. Try to engage enemy aircraft from behind cover and
at the shortest possible range, preferably just ahead or slightly
behind the aircraft using a low-angle deflection shot.
