Adding my BFV emblem in BF1

When playing BF1 I have notice players using a BFV emblem for their solider. Some are in a platoon and some aren’t. How do I use one of my BFV emblems to equip and use for my solider on BF1?
Whenever I want to create a platoon as well on BF1 it only gives me my custom and pre order emblems from BF1.
