What Is 173rd

Overview

The 173rd Airborne Brigade is one of the most storied units in U.S. Army history, known for its rapid deployment and combat readiness. Originally formed during World War I, it was reactivated in the 20th century as a dedicated airborne force capable of global response.

Today, the brigade is based in Italy and serves as the U.S. Army’s primary contingency response force in Europe, Africa, and the Middle East. Its legacy spans multiple conflicts, with a strong emphasis on airborne assault and special operations support.

• Established in 1917: The 173rd traces its lineage to a regiment formed during World War I, though it did not see combat until later reactivation.
• Activated on May 26, 1963: The modern 173rd Airborne Brigade was officially activated in Okinawa, Japan, under U.S. Army Pacific Command.
• First major U.S. Army unit in Vietnam: On May 5, 1965, the brigade deployed to South Vietnam, marking a significant escalation in U.S. involvement.
• Nickname 'Sky Soldiers': The unit earned this moniker due to its elite airborne training and frequent parachute operations behind enemy lines.
• Combat in Vietnam: The 173rd participated in over 15 major operations, including Operation Hump and the Battle of Dak To in 1967.

How It Works

The 173rd Airborne Brigade operates as a rapid-response combat unit trained for parachute insertion and air assault missions. Its structure allows for swift deployment and independent operations in hostile environments.

• Parachute Training:All infantry soldiers complete the U.S. Army Airborne School at Fort Moore, Georgia, mastering static-line jumps from aircraft at 1,250 feet.
• Brigade Structure: The unit comprises approximately 3,300 personnel, including infantry battalions, artillery, engineers, and support elements.
• Deployment Readiness: The 173rd maintains a 18-hour global response time, enabling rapid deployment via C-17 or C-5 transport aircraft.
• Command Structure: Led by a Colonel, the brigade reports to U.S. Army Europe and Africa for operational missions.
• Training Cycle: Soldiers undergo quarterly airborne operations and joint exercises with NATO allies to maintain readiness.
• Equipment: The brigade is equipped with M4 carbines, M240 machine guns, and Javelin anti-tank missiles, tailored for light infantry combat.

Key Comparison

This comparison highlights how the 173rd differs from other elite units in structure, mission, and deployment focus. While the 82nd and 101st are larger divisions, the 173rd functions as a brigade-sized, agile force optimized for rapid insertion.
