What does it take to rank up your BPR. I got it up by 4 ranks, but it now stop. I didn’t know how I rank up before. I went up with my kd whent up, so is kd a majpr part?

i think BPR means Battle Proficiency Rating (i mostlikely spelled that wrong) so im guessing you have to do good in matches to get it up.

BPR is based on kills, wins, assists, death & betrayals across all game modes of Reach.

Just hover over it on the stats page for a description.
