Lexington Institute lauds America's Premier Crisis Response Unit.

Daniel Goure talks about the MEU in his article.  A small bit...

Fortunately, the U.S. military has such specialized formations with the inherent capability to respond rapidly to a spectrum of crises ranging from the outbreak of conventional conflict to amphibious raids, special reconnaissance, terrorist incidents, non-combatant evacuations, humanitarian disasters and even partnership training opportunities. I am referring to the Sea Services' team known as the Marine Expeditionary Unit/Amphibious Ready Group (MEU/ARG). The MEU portion of the team consists of a reinforced infantry battalion supported by additional command and control, logistics and aviation elements.

Unfortunately for Marine Corps supporters and theorist the leadership is focused on the Marine Expeditionary Brigade instead of further leveraging and developing the capabilities of the MEU.  With budget cuts coming, it'll be interesting to see which one the Marine Corps bets its future on.
