Remember 23 October, 1983 Beirut Lebanon. 24th MAU....
 
 In the attack on the American Marines barracks, the death toll was 241 
American servicemen: 220 Marines, 18 sailors and three soldiers, along 
with sixty Americans injured, representing the deadliest single-day 
death toll for the United States Marine Corps since the Battle of Iwo 
Jima of World War II, the deadliest single-day death toll for the United
 States military since the first day of the Tet Offensive during the 
Vietnam War, and the deadliest single attack on Americans overseas since
 World War II.
 
 At around 6:20 a.m., a yellow Mercedes-Benz 
truck drove to Beirut International Airport, where the 1st Battalion 8th
 Marines under the 2nd Marine Division had set up its local 
headquarters. The truck was not the water truck they had been expecting,
 but a hijacked truck carrying the explosives. The truck turned onto an 
access road leading to the compound and circled a parking lot. The 
driver t
hen accelerated and crashed 
through a barbed wire fence around the parking lot, passed between two 
sentry posts, crashed through a gate and drove into the lobby of the 
Marine headquarters. The sentries at the gate were operating under rules
 of engagement which made it very difficult to respond quickly to the 
truck. Sentries were ordered to keep their weapons at condition four (no
 magazine inserted and no rounds in the chamber). By the time the two 
sentries were able to engage, the truck was already inside the 
building's entry way, armed.
The suicide bomber detonated his 
explosives, which were equivalent to 5,400 kg (12,000 pounds) of TNT. 
The force of the explosion collapsed the four-story building into 
rubble, crushing many inside. According to Eric Hammel in his history of
 the Marine landing force,
SEMPER FI, MARINES, RIP to all brothers lost.
