NPC skill brackets in T2k v.1

[raketenjagdpanzer]

Okay...this is driving me crazy. If you're on the FB T2k page, I apologize for making you read this post again, but on the off chance nobody over there can help me out, here's my plea again:

OK this is driving me bonkers. I've always just "winged it" but I could swear there was a rule covering skills for NPCs in Twilight 2000 v1.
Specifically, when you encounter a group of NPCs and there might be some need to engage in combat, use a weapon, etc., NPCs are given a value of Novice, Veteran, Elite etc. Where in the hell are the rules governing what those categories mean beyond a general idea?
I could swear up and down that there were brackets for percent values given for that and it was detailed in the damn rulebook.
If not I'll keep on just winging it but it's bugging the hell out of me.

Thanks all.
