I'm pretty sure they didn't start serious pvp before joining forces with 9 ghouls (Carnack, zvirak, soldier, barney, other buddies, selda and myself if I remember well). When we first met I remember around 4 or 5 guys, Napalm and Dendito included. Both of us had too low number to face the 12+ pistoleros swarm and the 8+ BBS.
They may have done some rambo action before in 2238 in reno or whatever, but I never saw them in TC before we gathered. The UV you knew until a few months ago was born out of that gathering. The UV you see now, well, Napalm'll tell you.
I played all 2238 sessions as a solo noob pve player (sometimes with a friend or 2) and I remember some famous factions names doing TC, but I can't remember any Ultra violence or anything close.
