This Sucks, U.S. AFRICOM is really "New", as created 2009.  Before that (2009) we were pulled from the U.S. Army Special Forces Groups and sent as Teams, usually from the U.S. Army's 5th Special Forces Group or the U.S. Army's 10th Special Forces Group.   After U.S. AFRICOM was created 2009, they got their Own U.S. Army Special Forces Teams Routinely assigned usually the U.S. Army's 3rd Special Forces Group.

What this means, is that U.S. Army Special Forces Groups have Areas of Operation, Team Members then become the Experts of that Area of Operation's Nations.  College or University Degree Level Cultural Anthropology of each Nation, language of those Nations are required to conduct the U.S. Army Special Forces Foreign Internal Defense Mission and or the Humanitarian Assistance Mission of Providing Health Care (Medical, Dental, Vision, this requires additional training to be a Physician's Assistant with Surgical Skills also as a Doctor with Surgical Skills recognized at other Nations)
