This is one of the oldest Middle East deployments of American troops you've never heard of

One of America’s longest Middle East deployments has been taking place since 1981. This is part of the Multinational Force and Observers in the Sinai Peninsula, which helps implement the 1979 Camp David Accords – the peace treaty negotiated by then-President Jimmy Carter between Egypt and Israel.

According to the State Department, the U.S. brokered the historic accords in 1978, with the peace treaty taking effect the following year. While that treaty is best known for the billions of dollars in military aid it has provided Egypt and Israel over the years, what is not as well known is the fact that a peacekeeping force was also established to keep the two sides at bay.

According to the MFO’s web site, the peacekeeping force was supposed to come from the United Nations, but that organization couldn’t get a Security Council Resolution approved. Israel and Egypt had to get together in 1981 to work out an alternative arrangement. The MFO was born out of those negotiations.

The United States provides the largest contingent of troops to this 1,365-person force. The American contingent usually includes an infantry battalion (either National Guard or active component) that serves a 9-month tour. The United States also provides a support battalion to back up not only its infantry battalion, but the troops from 11 other countries as well, including Australia, Canada, and Uruguay.

Colombia and Fiji provide the second- and third-largest contingents, respectively.

There have been fatalities during this mission. In 2007, according to a report by the Canadian Broadcasting Company, a DHC-6 Twin Otter crashed while trying to make an emergency landing. All eight personnel on board were killed.

In 1985, 250 personnel from the 101st Airborne Division were killed while returning from their tour, according to a Montreal Gazette report.
