As of right now when you check your service record for Fireteam Raven you are able to see:
Sessions played
Total Score
Total Enemy Killed
Accuracy
Then each individual mission with the following stats:
High Score
Max Kill Steak
Most Enemies Killed
Accuracy
Deadliest Enemy
If a stat could be added I would like it where if you scroll over a specific Fireteam Raven character in the individual missions, then it tells you the the High Scoreand Accuracy of that character and when you got it date wise
