Operation Sharp Edge was a non-combatant evacuation operation carried out by the 22nd Marine Expeditionary Unit (22nd MEU) and 26th MEU of the United States Marine Corps in Liberia in 1990 and 1991. The MEUs were supported by U.S. Navy Amphibious Readiness Group including USS Saipan (LHA-2), USS Ponce (LPD 15), USS Sumter (LST 1181), Fleet Surgical Team TWO and the destroyer USS Peterson (DD 969).
The First Liberian Civil War broke out in December 1989. Increasing violence between political and ethnic factions, including in the capital of Monrovia, had made it impossible for American diplomats and civilians to make safe passage to the U.S. Embassy to exit the country.
The 22nd MEU was composed of Battalion Landing Team (BLT) 2nd Battalion 4th Marines (ground combat element), HMM-261 (REIN) (aviation combat element) and MSSG-22 (logistics combat element).
Company "E" of the 2nd Battalion, 4th Marines executed a pre-dawn vertical envelopment of the besieged U.S. Embassy, with 237 Marines inserted via medium and heavy lift Marine CH-53E Super Stallion and CH-46 Sea Knight helicopters. The landing zones were under sporadic fire from light, medium and heavy weapons from belligerents. "Hotel" Company secured an extended perimeter around the U.S. Embassy and began evacuation of other allied embassies. Ground elements were supported by U.S. Marine AH-1T SuperCobra helicopters and Marine AV-8B Harrier II attack aircraft. Simultaneously, elements of BLT 2/4 secured landing zones in the surrounding areas, extracting U.S. and foreign nationals. Non-combatants were flown off to the USS Saipan (LHA-2) and USS Ponce(LPD-15) for processing and ultimately Freetown, Sierra Leone. Although BLT 2/4 conducted the initial entry into the embassy, the Marines of BLT 3/8 with 26th MEU arrived on station and continued with the evacuation operations as the 22nd MEU began its retrograde and departure.
