There will be an enemy with a sniper on the roof of a building on the top left side. Crouch behind the large trash bin on the right and start taking them down. Turn the corner and you'll see a handful of enemies ready to gun you down. But again, if you don't have any ammo for it, any other gun will do. A quick shot with your RPG will take them out immediately. Walk past the car and two motorcycles holding four more enemies will show up.
If not, any other gun will do, but stay behind the brick wall on your right-hand side for cover.
If you have an RPG or some Remote Explosives, go ahead and use that to take them out quickly. The first four enemies will get out of the car and start shooting at you. Get Out of the Alleyway and Protect Woozie A car will then speed through the gate, and you'll have to take on a few enemies while keeping Woozie alive. There's been an ambush and the Da Nang Boys have taken out the Triads.
