You are in control of a two-man squad; you may have noticed a soldier following you.  Press the "Hold position" key on your keyboard (defaults to "H").  This tells your squad to stop following you around.  Press the "Follow" key to get them to follow you again (defaults to "F").  Now press the "Hold Fire" key (defaults to "J") and walk over the hill in front of you until you get to the next Training Area sign.  When you see the enemy soldiers, do not fire on him.  You are invisible in this tutorial so the enemy is no threat.
