States. By 1964, the Army had reached the conclusion that the Pentomic arrangement didn't work, and the 101st returned to a more recognizable structure. The Department of the Army announced that brigades would be the building blocks of the new style divisions. Consisting of three battalions with wartime attachments, they were similar to what used to be called a regiment or regimental combat team; however, the 502d found itself split. The HHC 2d Battalion (with the lineage of Co B/502PIR) was in 1st Brigade with two battalions of the 327th, and HHC 1st Battalion (with the lineage of Co A/502PIR) was in 2d Brigade with two battalions of the 501st. Vietnam War In April 1965 the 1st Brigade was deployed to South Vietnam to relieve the 173rd Airborne Brigade. Instead as the war expanded, both units stayed. The 2d Battalion, 502d Infantry quickly made a name for itself under the command of LTC Henry E. Emerson.

The Napalm attack injured seven of Carpenter's men, but the PAVN ceased fire long enough to allow Company C to consolidate, reorganize and establish a position from which to defend and begin evacuation of wounded personnel. For their extraordinary heroism in destroying the PAVN and in evacuating the mass casualties, both Carpenter and 1st SGT Walter Sabalauski received the Distinguished Service Cross. The Fort Campbell Air Assault School was named in Sabalauski's honor. Another member of 2-502d was CPT Tommy Taylor, son of General Maxwell Taylor, who wanted to serve with his father's wartime command. In 1967, Operation Eagle Thrust moved the rest of the division to South Vietnam aboard chartered airliners as part of the American buildup. At that time it was the largest single airlift in US military history. Unfortunately the orders for it found the remainder of the division on Fort Campbell not ready to enter the
