What determines medals?
 

Anyone got any pattern to when metals are awarded and which ones?

I think it is the amount of tonnage you sink each patrol.

A series of medals is awarded for tonnage sunk in a single patrol, while most of the others count total tonnage sunk throughout the campaign.

Then there's the Purple Heart, which depends on you being wounded when abandoning ship, I think?

I did the hd mod with rewards for the Soviet side(it can be downloaded at (Subsim),it's just a revision of the mod (New Playable Subs & More),but I'm interested in how you can extend the rewards to the company(which files to modify) that would be rewards for the Soviet side would be as written by comrade Shadow -like here http://www.subsim.com/radioroom/showthread.php?t=232424 if anyone knows tell me.

I know it's just for fun but it would be nice to get a bonus for sinking certain high value targets like the Kirov, Kiew, Oscar, etc.

No,I'd like to try to separate the receipt of new awards (such as the Order of the Red Star,Order of Nakhimov) on the importance of the tasks,but by tonnage the same,but can't achieve a result (by changing files in the game) what would the awards show.
