A message appears at the top of the screen each time you earn a new promotion.
Almost every action performed in a multiplayer match can earn you points. Points not only determine which players are listed at the top of the scoreboard after a round, but they also help you unlock new weapons, gadgets, specializations, and even achieve new ranks.
So at the end of a round, check out your overall performance in the End of Round screens. These screens show your current rank as well as your progress toward achieving the next rank. It also has statistical breakdowns of your score, showing how many points were earned with each kit, vehicles, and awards.
Speaking of awards, any dog tags, medals, or ribbons earned during the round are shown in the Unlocks and Awards sections. The Kits screen shows how much progress you’ve made toward unlocking new equipment for each kit.
