Extra med kit
If you see a swimming pool there will be more than likely a hot babe there. Search the perimeter of the pool until you see her. When you do see her, the sniper will say, "wow!", and your headset will say, "hold your fire." Then if you look at your heath meter you will see that there is an extra med-kit.
