+This file defines patrols in game.
+
+Fields index:
+	Size			- base number of soldiers in patrol. Actual number of soldiers is
+				  calculated as base number plus/minus 1 and then max/min limits
+				  are applied. Max limit is MAX_STRATEGIC_TEAM_SIZE in INI, and
+				  min limit is *_MIN_ENEMY_GROUP_SIZE. Provide integer number.
+
+	Priority		- Hmmm... Priority is priority. It defines importance of patrol
+				  group to Queen. More important - more chances to get reinforcements,
+				  more chances to upgrade admins to regular troops. Provide 
+				  value from interval [0..100].
+
+	Waypoints		- this categiory define route of patrolling group. You are given
+				  up to 4 (2 is a minimum) sector check-points. At a check-point
+				  patrol can change direction of movement. Only horizontal and
+				  vertical movement is allowed, diagonal is restricted. In case
+				  short routes (e.g. 2 or 3 points) fill unused sectors with 0.
+				  And also you cannot use sector A1 in routes. Patrol moves through
+				  route like a ball in ping-pong, e.g. ...-1-2-3-4-3-2-1-2-3...
+				  Starting point is random.
+				  
+	Sector1..4  		- it is where patrol will be coursing. Provide valid sector name
+				  or 0, if this field is unused.
+
+NOTE: Maximum 50 patrols can be used in game.
