I think you just mean the K/D ratio... It's your kill to death ratio and for Halo 3 you can see it by going to your Halo 3 service record and clicking on any of the medals at the top.
Hahahha this guy ^^^^^ is a dumbass. It means your Kills plus your assists, divided by your deaths. You can't see this on bungie.net, but if you have a halocharts.com account you can calculate this. I personally like this better, because if you are a great assist player your ratio is higher.
