Marines began peacekeeping in Lebanon in 1982, when U.S. forces were deployed to Beirut as part of the Multinational Force in Lebanon to stabilize the country during the Lebanese Civil War and after the Israeli invasion. This deployment marks the start of the Marine peacekeeping presence, not 1983 or 1984, which came after the initial arrival and during the ongoing mission. The event in 1983, the Beirut bombing, showed the danger of the mission but did not initiate it.
