The entity has a Scout command in the GUI. Once put into Scout mode, the entity moves methodically back and forth through an enemy's Civ Territory in ever expanding arcs to reveal the terrain/entities there.

When it reaches the edge of the map, it will begin working its way back in ever-decreasing circles until it returns to its point-of-origin (presuming it survived to do so), and continue the cycle ad infinitum.

More than one scouting entity may be placed into a Flanking Formation which will reveal a broader swath of the terrain on each pass as it continues to Scout.

Example:

        <Actions>
  		<Scout />
  	</Actions>
