Playercards with no description

[JarskyPlays]

Does anyone know how to unlock these Vehicle cards?

Are they supposed to have descriptions that give us a hint as to how to unlock them? 

I cannot find any info about them, I assume Tread Lightly is a tank based one, and Ravenous is a Heli based one but no idea what is the criteria. 

I have thousands on thousands of kills (infantry & vehicles) in the stealth helis and plenty of repairs so no idea what I havent done to get this card at least...

They’re probably upcoming bundles not released yet. My bet is next Tuesday they’ll be available to buy.

Usually those who are showing in the playercard list already but have no description are new ones that will be available through bundles in the store but these specific bundels are not added in the store yet. 

Thats why the description is missing at this time.
