Flying RPG man:
Slightly before halfway through level 4, “Travel To The Airport”, you will go through a narrow tunnel on your right. Continue until you see a SHTURM (missile launcher) near a building. Defeat it and continue left before the building. Shoot the watchtowers from a distance. When you come near, the man floats in the air even though the tower he stands on has been destroyed. He can still shoot — attack him with a grenade.
