Relative Location Method

The Relative Location Method
The Relative Location Method consists of gauging your position from the targeted fleet (ex.Front-Left, Front-Right, Rear, etc.)

Targeting Freighter/Tanker Only Fleet (No Escort Ship)

 * 1) Calculate the course for the intended fleet on the tactical map and click the drop down menu in the mission box to change your fleet's position to either the front left or front right of the target fleet, it is recommended that you do this either with auxiliary u-boats, or multiple Type II A, Type II B, or higher U-boats.
 * 2) Once the mission has started your sonar operator should almost instantly give you a bearing for a sonar target followed by either single ship or convoy.
 * 3) If the sonar target is a single ship, ignore it.
 * 4) If the sonar target is part of a convoy, raise your periscope just above the water line to avoid being spotted.
 * 5) Set a course for the bearing your sonar operator gave you earlier and pursue it at full throttle while remaining at periscope depth.
 * 6) Keep ordering sonar reports regularly and adjusting your course until you get a visual on the target fleet.
 * 7) Once a visual has been established, lock on to the nearest ship and flood the appropriate tube to check if the ship is within range.
 * 8) You now have two options, you can either (A) trust your u-boats officers and wisely order your weapons officer to calculate the torpedo solution or (B) Take a risk and try to calculate the solution yourself. Either way it is wise to first perform target reconnaissance to determine valuable information on the target ship.
 * 9) If you chose to have your officer calculate the solution, fire immediately after he is finished.
 * 10) If not get in closer and aim ahead of the target ship, otherwise you will ensure you miss the target and waste a torpedo. DO NOT FIRE A SALVO UNLESS YOU ARE WITHIN 300m OF THE TARGET SHIP. OTHERWISE ONE OR ALL OF YOUR TORPEDOES WILL BE WASTED.
 * 11) If only one torpedo hits the target ship, repeat 7-10 until you hit it a second time, it takes no more and no less than two hits to sink a freighter or tanker.
 * 12) Once the target has been destroyed or you run out of torpedoes, set a course away from the convoy.
 * 13) Begin Surfacing
 * 14) Set course to nearest port or home port
 * 15) Mission complete, now refuel, rearm, and reengage.

Targeting Freighter/Tanker Fleet with One Escort Ship (Passive Variant)

 * 1) Calculate the course for the intended fleet on the tactical map and click the drop down menu in the mission box to change your fleet's position to either the front left or front-right of the target fleet, it is recommended that you do this either with auxiliary u-boats, or multiple Type II D, Type II E, or higher U-boats.
 * 2) Once the mission has started your sonar operator should almost instantly give you a bearing for a sonar target followed by either single ship or convoy.
 * 3) If the sonar target is a single ship, ignore it.
 * 4) If the sonar target is the escort ship, avoid it at all costs.
 * 5) If the sonar target is part of a convoy, and is not an american warship, raise your periscope just above the water line to avoid being spotted.
 * 6) Set a course for the bearing your sonar operator gave you earlier and pursue it at full throttle while remaining at periscope depth.
 * 7) Keep ordering sonar reports regularly and adjusting your course until you get a visual on the target fleet.
 * 8) Once a visual has been established, lock on to the nearest ship and flood the appropriate tube to check if the ship is within range.
 * 9) If you have not already, find out where the escort ship is and avoid it at all costs. DO NOT LET THE WARSHIP SPOT YOU IF POSSIBLE.
 * 10) You now have two options, you can either (A) trust your u-boats officers and wisely order your weapons officer to calculate the torpedo solution or (B) Take a risk and try to calculate the solution yourself. Either way it is wise to first perform target reconnaissance to determine valuable information on the target ship. DO NOT APPROACH THE WARSHIP
 * 11) If you chose to have your officer calculate the solution, fire immediately after he is finished.
 * 12) If not get in closer and aim ahead of the target ship, otherwise you will ensure you miss the target and waste a torpedo. DO NOT FIRE A SALVO UNLESS YOU ARE WITHIN 300m OF THE TARGET SHIP. OTHERWISE ONE OR ALL OF YOUR TORPEDOES WILL BE WASTED.
 * 13) IF ABSOLUTELY NECESSARY, ELIMINATE THE WARSHIP FIRST. OTHERWISE CONTINUE AVOIDING THE WARSHIP.
 * 14) If only one torpedo hits the target ship, repeat 7-10 until you hit it a second time, it takes no more and no less than two hits to sink a freighter or tanker. If the target was near the warship, set a course away from the convoy at full throttle.
 * 15) Mission complete, now refuel, rearm, and reengage.

Targeting Freighter/Tanker Fleet with One Escort Ship (Aggressive Variant)

 * 1) Calculate the course for the intended fleet on the tactical map and click the drop down menu in the mission box to change your fleet's position to the front left of the target fleet, it is recommended that you do this with only Type II E or higher U-boats.
 * 2) Once the mission has started your sonar operator should almost instantly give you a bearing for a sonar target followed by either single ship or convoy.
 * 3) If the sonar target is a single ship, ignore it.
 * 4) If the sonar target is the escort ship, set an intercept course for it while remaining at periscope depth
 * 5) If the sonar target is part of a convoy, and is not an american warship, raise your periscope just above the water line to avoid being spotted.
 * 6) Set a course for the bearing your sonar operator gave you earlier, or the escort ship's bearing if you know it and pursue it at full throttle while remaining at periscope depth.
 * 7) Keep ordering sonar reports regularly and adjusting your course until you get a visual on the target fleet and identify the escort ship.
 * 8) Once a visual has been established, perform target reconnaissance on each ship one by one until you find the escort ship.
 * 9) Once you find the escort ship, lock on to it, and flood the appropriate torpedo tube(s).
 * 10) You now have two options, you can either (A) trust your u-boats officers and wisely order your weapons officer to calculate the torpedo solution or (B) Take a risk and try to calculate the solution yourself. Either way it is wise to first perform target reconnaissance to determine valuable information on the target ship. Approach the warship.
 * 11) If you chose to have your officer calculate the solution, fire immediately after he is finished.
 * 12) If not get in closer and aim ahead of the target ship, otherwise you will ensure you miss the target and waste a torpedo. DO NOT FIRE A SALVO UNLESS YOU ARE WITHIN 300m OF THE TARGET SHIP. OTHERWISE ONE OR ALL OF YOUR TORPEDOES WILL BE WASTED.
 * 13) Eliminate the Warship.
 * 14) If only one torpedo hits the escort ship, repeat 9-13 until you hit it a second time, it takes no more and no less than two hits to sink a freighter or tanker. If the target was near the warship, set a course away from the convoy at full throttle.
 * 15) Eliminate other ships if you have sufficient torpedoes
 * 16) Mission complete, now refuel, rearm, and reengage.
