Vietnam-Germany-Fort Irwin: the Eaglehorse and the M551 Sheridan

From the rubber plantations and rice paddies of Vietnam to icy tank trails at Grafenwoehr, to the red-yellow dust of Fort Knox to Panama and Fort Bragg and dozens of National Guard hardstands and then rapid deployment to Saudi Arabia in support of Desert Shield to finally masquerading as threat armor in the California deserts at Fort Irwin, for the M551A1 Sheridan tank, it has indeed been a long and strange ride. A thoroughly new concept in tank design, the first models came to active service in Vietnam in 1969, the last of the fleet will be phased out at Fort Irwin in early 2004. Three generations of US Army tanker-scouts served on this vehicle.

Troopers of the Blackhorse Regiment and Eaglehorse Squadron played an active role in many of the major chapters of the story. They painted on the first bumper numbers in Vietnam and will scrape off the unit designations at Irwin during final turn-in. They lived with them, died with them, struggled and cursed, kicked butt at the NTC and broke down on the Autobahn. Most of the Sheridans could run all day, many could fire the main gun and hit, the missile launch was a big thrill at Level 1 gunnery for a lucky crew, SSG Pharris and crew of Troop G 2/11 ACR got to do it all.

We tell the story of the Sheridan at both the crew level and as a fascinating insight into how the best intentions of engineers, manufactures, politicians and career military men can become part of a program going clearly wrong. Long after the M551 had been largely withdrawn from active combat units, the memories of the program had a lasting effect on the design and procurement of future Army tanks. Much of what was done right with bringing M1, M2 and M3 through the design and manufacturing phase and then into the inventory can be traced back to lessons learned from the Sherdian program.

The Eaglehorse and the Sheridan is a long and complex story, rich with detail; we have tried to craft the text in manageable sections. The first three portions consider the evolution of US armor vehicle design and procurement that led to the decision to produce the M551, then Sheridan OST at Fort Knox and combat experiences in Vietnam. The history, design and development text is heavily sourced from R.P. Hunnicutt's seminal work, Sheridan: A History of the American Light Tank, Presido Press, LTC (Ret) Burton S. Boudinot's article "A Sheridan Memoir: The Early Days", Armor Magazine, Jan-Feb 1997, the article "Soldiers" by Ward Just, Oct-Nov 1970 Atlantic Magazine and the archives of the Cleveland Press and the New York Times. The Vietnam section is built with recollections of Col (Ret) Clint Ancker, LTC (Ret) Lee Allen, and major text and photo contributions from Doug Kibbey and Roy Lingle. As the Sheridan story turns to Germany and Bad Kissingen, Col (Ret) Norman Harms, and Terry R. Smith provide details covering the fielding of the vehicle to the 2/14 ACR.  A mini photo album with scenes of the fielding was contributed by the family of Gary Bell.  After the re-flag to the 2/11 ACR, Col (Ret) Anker, Col (Ret) Chris Conrad, LTC (Ret) Lee Allen, Col Mike Heredia and Bob Stefanowicz pick up the story. Continuing towards the present, the M551 becomes a micro fleet of specialty vehicles at Fort Bragg and Fort Irwin, Bobby Haig and Doug Kibbey tell the story with great text and photo contributions. In our summery, we briefly reconsider the Sheridan program and examine the role of memory and the last running M551.

Our photos come from a variety of sources, the Hunnicutt work, 14th ACR unit yearbooks, TMs and donated images from various troopers from Vietnam to Germany and the NTC. We are always searching for additional images and hope that you will consider helping us out.

For anyone wishing to study the story of US armor vehicle development in the post war period, the works of Mr. Hunnicutt are highly recommended. They are in print and can be special ordered through many major book outlets.
