I think Rostosov has the highest kill count so far: 2 kills, shooting for 3 with Irina. If I manage to kill Daemon, I would have two as well, making Irina the tiebreaker if she survives.

At the end of the day, it sounds like Harold is gonna be promoted. He tried the most to actually lead the team, and he was one of the ones to best complete the objective "defeat as many as you can".
