How to Reset Multiplayer Progression

I have recently just purchased another copy of Battlefield 4 after about a year of playing and I still have all the progression I had from the last time. However, I feel that I would like to start again, no progression, no awards, no unlock - nothing. A total progression reset so that I can start from Level 1 and play through from the beginning. I cannot find anything to help me - how do I reset my progression on Battlefield 4 Multiplayer!
