Wiki sez:
Commander Score
The commander score is the sum of all commander points earned. The commander points are every point earned by a member of your team during your reign as commander divided by the total of living team members at the given time. This is multiplied by two at the end of the round, when your team wins, and only if you are still active commander at the end of the round. Artillery kills or any personal achievement does not add up to this number. Personal achievements besides artillery kills are added to your points in the round, and count as combat or team points.Try to keep your squads from from dying, so they can kill enemies, capture flags and destroy enemy assets.
This means support them with UAV, satellite scans and vehicles.
Try to avoid friendly fire with the artillery. Use the warning message.
Although, the more players there are on a server, the higher the probability that there is someone with a higher rank also applying for commander.
