First Order Stormtrooper designation?

[zb30[501st]]

So First Order Stormtroopers have the same "TK" designation as the Original Trilogy Stormtroopers within the detachment here.  Why is it that they do not have their own individual designation?   Like "FN" for example.  The Clones have different designations, AR, TC, CT, CC, CP, RC & CX.. So I just find it odd that FO is the same as OT.   Forgive me if this has been asked before, I know I'm a newbie.

A major discussion has been held here and on the main boards, they do use TK a couple of times in the movie so the word is it's staying TK for now

I just read through that thread, now I can see why they have decided to leave it TK.  Thanks!
