The last half of the 24th MEU's 2012 deployment focused on their duties as an expeditionary crisis response force. After the attack on the U.S. embassy in Benghazi, Libya, the MEU began extensive planning for potential missions to aid and/or evacuate U.S. citizens throughout the region in a number of countries that included Sudan, Lebanon, Egypt, Yemen, Tunisia, Syria and Pakistan. The threat of regional unrest resulted in an extension in the 5th Fleet area of responsibility. The MEU was later extended in November to continue serving as a ready, crisis response force throughout the Mediterranean region in 6th Fleet. This second extension led to the MEU returning home a month later than originally scheduled. They returned to North Carolina on 20 December 2012
