In September 2013, 3/7 returned to Northern Helmand province and relieved 3rd Battalion, 4th Marines, in Afghanistan for a third tour in support of Operation Enduring Freedom. The Battalion conducted distributed operations providing support to the Afghan Security Forces with companies located in Musa Q'ala, Sangin, Kajaki and FOB Shukvani in the Southern Musa Q'ala Wadi. This deployment was much different than the two previous as the Battalion was focused on supporting the Afghan Security Forces and conducting retrograde operations by transferring the Combat Outposts to the Afghan National Army. India Co, as well as Kilo Co, tactically enabled by British SAS and Afghan Special Forces, conducted various offensive operations in 5 districts within Afghanistan.
