Green Beret/Airport (NES only)

The first soldiers to attack you in this level are wearing a darker red or maroon color. Make note of this so that you can distinguish between them and the combat specialists who appear next and wear a lighter shade of red. Additionally, sniper soldiers will appear in some of the watch towers, and gun soldiers will appear on the ground in yellow. If they fire, be sure to duck. Note that a sniper can't shoot you while you stand directly beneath his tower. This stage also contains a number of land mines on the floor to watch out for, and take special care jumping over land mines when an oncoming combat specialist appears on the right. Always time your jumps over the mines to coincide with their jump attacks. Supply runners typically appear on top of trucks.

There are a number of situations that you want to watch out for in this stage. Also avoid letting a yellow gun soldier follow you for too long. Invariably, a combat specialist will show up on the right when the gun soldier decides to fire. You can't leap and crouch at the same time, so you will get hurt. Also avoid leaving a yellow gun soldier behind you when you enter the sniper tower section near the end. Once you stop to avoid a gunner's bullet, the sniper bullets will hit you. Finally, supply runners are typically situated in place where the resulting weapon will fall down to the ground below. Do not fall down after the weapon, as a combat specialist typically appears as you are falling. You will not have enough time to hit the ground and jump again to attack the combat specialist before he jump kicks you.

The final battle in this stage involves a confrontation with three jet pack equipped grenadiers. The will appear on the screen together and hover some distance above the fence dropping grenades on you. Occasionally they will dive down low enough for you to jump up and attack them. In order to advance, you must strike all three. The trick to defeating them is to move only when necessary, e.g. when a grenade is about to fall on you. The reason for this is because they will drop down right within range of your attack to the left or right. If you move around, you will have to reset your position before you attack and by then, they may fly back up again.
