Negative Teamwork Scores?

[GRAVEWALKER]

I've been experiencing alot of negative teamwork scores, but I'm not TKing people (well as few as possible). I realized that blowing yourself up with C4 is -2 teamowrk score. What other things give you negative teamwork score? Apparently I need to find this out. Help appreciated with my gratitude.

switching team when alive is another -2

Doing damage to a team vehicle also causes negitive scores, even what you'd consider a minor scratch can sometimes cause this.

destroying a friendly support sentry gun is the pain in my side, they seem difficult to identify as friendly or not sometimes when you come across them randomly

If you're ever approaching one from an angle it can't see you at then there is no immidaite need to shoot it, simply hover over it for 3 seconds and see if a red or blue icon appears, i've never had that fail to identify it for me. Not sure if its working for everyone though.

Thank you folks for the help. Apparently you REALLY have to be careful.

Killing yourself will do it, too.

/thinks suiciding should be no penalty

No please dear god no, if they removed the suicide penatly people would be suiciding to deny the enemy kills like when being sniped if they had no cover they would suicide out of spite. It happens in PlanetSide, it would happen in BF.
