US Navy Seabees assigned to Naval Mobile Construction Battalion 7, or NMCB-7, disembark from a C-130 Hercules in Gulfport, Mississippi, on 5 May 2010 after a four-month deployment to Haiti in support of Operation Unified Response. NMCB-7 was among the first U.S. ground units to arrive to provide humanitarian relief following the magnitude 7.0 earthquake that struck the island nation in early 2010. The C-130E aircrew was from the 156th Airlift Wing, the Puerto Rico Air National Guard unit at Luis Muñoz Marin Airport in San Juan.
