This perma perk gives you 1000 point everytime you buy a perk i.e: Quick Revive, Juggernog, etc., and go prone. You get this perma perk by going prone after when you buy any perk. It takes a while but you'll know if you have it when that green spark appears. You lose it if you don't go prone within 5 sec of buying a perk. It's a tough perma perk to keep.
