How does OFP calculate mission scores?

This is a much discussed topic and I have not seen anything definitive on this to date.

Player Wouter van Gulik has compiled the following information on the subject. Anyone with additional information or corrections is invited to contact yours truly. Just make sure you've got all the details on how you've arrived at your conclusions:

• 200 points for killing an enemy regular soldier (no matter what kind of soldier, rocket, MG, crew, etc.).
• 1000 points for killing an enemy officer or spec-ops.
• 200 points for destroying a BMP, Shilka, MI-17, UAZ, etc.
• 1000 points (not sure about this) for destroying a T80.
• Killing your own teammate will get you negative points. Don't know exactly how much.
• -40 points if a soldier under your command is killed.
  

You will get points for achieving your mission goals, which will vary from mission to mission of course.

Note that sometimes enemy units die but you don't get any points. Try shooting a group of 3 soldiers with a law/RPG. Sometimes you'll just get 400 points, sometimes 200, sometimes 600.
