The 2nd Battalion, 327th Infantry Regiment, known as the "No Slack" Battalion, is a storied unit of the 101st Airborne Division (Air Assault) in the United States Army. Originally activated on August 5, 1917, as Company B, 327th Infantry, the battalion has served with distinction in major conflicts including World War I, World War II, Vietnam, Iraq, and Afghanistan. Its "No Slack" nickname was earned during the Vietnam War, where the unit endured continuous combat operations from 1965 to 1972 without being pulled from the fight. Today, the battalion remains a vital air assault force, trained to rapidly deploy and engage in high-intensity combat operations around the world.
