What Does T.O.W.E.R. Stand For?

So far I have resisted trying to give the specific words which lead to the acronym T.O.W.E.R. but the organization features strongly in the next Masks story. So far I have: Theater Overwatch World Enforcement Regulator. That doesn't really... work, so I am looking for suggestions.

This is not a contest. The only reward will be the use of the name in the story.
