I can confirm as one of the TU members and a former TUO. Its a cool Unit and a great Idea, but it had 2 options medic and support (Which isnt useable because the shotgun does not work) and not all people want to do those jobs, and especially not after they get ARC trained. The vast majority of people that join TU leave as soon as they get ARC trained because why would you not want to use the equipment that you earned. That is also just the main goal of the average new Rancor member, to get ARC trained so that they can move to Heavy, Support, or Medic within normal Rancor. Most people are not going to shoot themself in the leg to stay in a unit that is mediocre at best and just forgotten about by the populus of the server. It's just hard to keep a Sub-unit of non ARC in the battalion that is known for ARC. Traumas Unit just sadly doesn't fit.
