> Find a rock to knock out the guard with.

You look down, and find a rock laying on the ground! Convenient!

> Check surroundings.

You take a look at the map that your Colonel has supplied you with:

You notice that your location is marked on your map in green, as graciously stated by the text "You are here".

You also notice that the guard has now been marked on your map in red. (Will only show up on map when visibly seen!)

You also take note of the blue arrows on your map. (You may choose one of these blue arrows in a command to pan and reveal more of the map!)
