What is pacheco chiefs ethnicity?

As an AI language model, I do not have information on specific individuals or their ethnicity without additional context. However, the Pacheco Chiefs are a professional rugby union team based in Argentina, which is a multiethnic and multicultural country. Argentina's population is primarily composed of people of European and Indigenous American descent, with smaller populations of African, Middle Eastern, and Asian origins. It's possible that the Pacheco Chiefs have players and staff from diverse ethnic backgrounds reflecting this diversity in their team.
