Saving missiles
You can shoot fuel barrels and other explosive objects that are
next to targets with your cannon to receive extra damage without the
use of missiles. Just save your guided missiles for other
helicopters.
Level 1: Easy kills
After you pass stealth training and return back to the base it
will be under attack. When you get to the front of the base go into
stealth mode. Stun the tanks, half tracks, and jeeps, then shoot the
men.
Surprise kill
Remember to stay below a hilltop, hiding from enemies, rise up,
fire a few rounds, then drop back down to dodge return fire.
Long distance shot
You need to use the sniper scope to zoom in on far away
enemies, then shoot them with the unguided rockets or cannon even
without having a lock.
See enemies easily
The thermal scope can be used during the day to easily
distinguish vehicles and soldiers.
