Tyler Cross, infantry Marine, Battalion Landing Team 3/1, 13th Marine Expeditionary Unit (MEU), writes down the repetitions aboard the Whidbey Island-class amphibious dock landing ship USS Rushmore (LSD 47) at sea, April 26, 2018. The Essex Amphibious Ready Group (ARG) and 13th MEU integrated to conduct the second major exercise of their pre-deployment training. ARG, MEU Exercise (ARGMEUEX) provides essential and realistic ship-to-shore training, designed to enhance the integration of the Navy-Marine Corps team. ARGMEUEX provides an opportunity to integrate unique individual and unit skills and develop the Essex ARG and 13th MEU’s collective proficiency in challenging and unfamiliar environments.
