This is a joint operation mission with Ranger 2-1(from the Columbia campaign), and Echo 2-7(from the Iran campaign.) You play as Delta 5-1. Your mission is to infiltrate an enemy airfield. Take down 3 AA guns for 2 chalks of Rangers so they can start their assault. You'll infiltrate by boat, and start your attack on the beach. Make your way through the beach, and reach the enemy fortress. After the fortress, the path should lead you to the airfield. Once all objectives are complete, Romeo 3 will pick you and your team up. Good luck.
