1st Battalion 9th Marines

The 1st Battalion 9th Marines (1/9) was an infantry battalion of the United States Marine Corps. Formed during World War I, it served until the mid-2000s when it was deactivated to make room for one of three light armor reconnaissance battalions. During the Vietnam War, 1/9 sustained the highest casualty rate in Marine Corps history. This earned them the nickname "The Walking Dead". As of 29 August 2014 the battalion has once again been deactivated due to a force shaping initiative and downsizing of the Marine Corps.
