The M551 Sheridan And The Army’s Light Tank Problem
The M551 Sheridan was supposed to be the Army’s answer to an impossible problem: build a light tank that could be air-dropped with paratroopers, survive the battlefield, and still kill enemy armor. What the U.S. got was a strange Cold War machine with aluminum armor, a massive 152mm gun, the Ford-built Shillelagh missile, and a reputation that people still argue about. In this video, we break down the full story of the M551 Sheridan, from its origins as an airborne light tank for the 82nd and 101st Airborne, to its troubled service in Vietnam, Operation Just Cause in Panama, Desert Storm, and its long afterlife at the National Training Center. We also look at why the Army kept trying to replace it with programs like the M8 Armored Gun System, the Stryker Mobile Gun System, and the M10 Booker, only to end up right back where it started. If you want the history of the Sheridan tank, the Shillelagh missile, Army light tank programs, airborne armor, and why the U.S. still cannot field a true air-droppable tank, this one is for you. 00:00 - Intro 01:07 - The need for the Sheridan 03:09 - Designing the Sheridan 06:09 - The Sheridan’s problems 07:46 - The Sheridan in Vietnam 10:51 - Sheridan vs. Soviets 12:58 - Operation Just Cause, Desert Storm, and NCT 16:59 - Channel Updates Recorded on: April 7th, 2026 Written by: Kyle Gunn Edited by: Savvy Exciting armor articles: https://www.lightmetalage.com/news/in... https://www.constellium.com/news/alum... https://www.totalmateria.com/en-us/ar... https://www.sae.org/papers/applicatio...
