Sniper Fort in Minecraft

Choose any block that you can build on,and a slab. The type doesn't matter

Make a closed frame of any size.

Build up two more blocks to make the walls.

Make a roof of any kind.

Cut out a hole in the front of your fort with at least one block on either side (see picture)

For the slit you'll need some slabs.Place them on the bottom half of your sniper hole.

For the entrance you can put a door or a underground tunnel.

For lighting you could use torches or glow stone. Your choice.

You could put a chest in the corner to store items such as bows,arrows,etc.

You can make a "hidy hole" in the corner for protection in case things get rough.

Now your sniper fort is done.Awesome accuracy inside,but hard to get hit inside.p.s. This structure is great for hunting mobs such as skeletons.
