The 26th MEU is on call. Why a new SPMAGTF?

To almost no fanfare, the USMC stood up a new Special Purpose Marine Air-Ground Task Force based out of Sigonella.

Why is this important?

Because the 26th MEU is afloat off the horn of Africa.  Because the Marine Corps also deployed another SPMAGTF-12 (Africa) to do training missions with African States.

Because the USMC has officially stood up a SPMAGTF that is based off getting to battle with MV-22's and KC-130's.

This is a step back from getting feet wet again.  It also goes

against the best case for joint operations.  Its dabbling in Army roles and missions.  Ever heard of the 173rd Airborne Brigade Combat Team?  They're Europe's strategic reserve and in a pinch can be deployed far and wide...to include locations in Africa.

This doesn't count the Special Forces Group that has Africa as part of its geographic area of responsibility.  It also doesn't include the Army Rangers that are capable of deploying and responding to flash points quickly.

For some reason during a time of austerity, the USMC head shed has chosen to duplicate missions that are already being performed by a US Army Brigade Combat Team, various elements of SOCOM (that I know about) and US Marine Corps Marine Expeditionary Units.

I would like a simple answer to a simple question.  Why?
