Forum:Stormtrooper id codes?

Hello every one.

I was just wondering if the Stormtrooper ID codes mean anything.

I don't know if I'm getting the name right so i will give some examples

TK-421 TK-422 TK-8252 (those are all grabbed from the stormtrooper page.)

So what I'm asking is if the TK part stands for something or if its just there to identify ALLL the stormtroops apart.

and srry if i made this the wrong why this is my first post...and these forums are a lot different then normal other forums I've been to.
