Deer found in Far Cry 3 are small. They do not have very large horns, and run from loud noises and predators like a human carrying a large firearm. They can be killed and skinned. These skins can be used to craft some lower level equipment upgrades. At least five pieces of deer hide are needed for Crafting harnesses and pouches. You are to be provided a Sniper Rifle to go hunt deer to help feed hungry Rakyat families. Once this side quest is accepted you will be directed to the East. Just start along the road nearby the Docks and up the hill. Stay on the road and it will be easy to reach your destination. Collect the Sniper Rifle and fill up on ammo. This is tricky by virtue of there are 5 deer that you need to hunt and kill. With the Sniper Rifle it means that you can get them with only a shot or two. However it also means that the small herd will scatter quickly after the first one goes down. To make your life easier, pull out the camera first to mark them all. Even with Hunter's Instinct to help you out, it is better to take some time to just have something fixed on them. Take your time and hunt them down individually. It will take a little while but you will get your reward before too long.
