The Sheridan Reconsidered
"Lucky One"
Viewed now, the M551 program seems like an appalling collision of
designer’s good intentions, engineer’s promises and military dollars
tied to a vehicle often thrown at tasks it was never designed to
perform. Just when someone should have said "let’s wait", they said
, "let’s go". Too much money had been committed to delay the program
any further and in light of the Cold War, the line of thought often
was, an imperfect tank was better than none.
In retrospect, this was not all that uncommon in big budget weapons
systems procurement of the time. What should have been the most
basic and carefully considered equipment evolution, the fielding of
the new M16 rifle to the US military in the mid 1960s, was marked by
scandal and controversy. In the height of the Vietnam War, the rifle
powder didn’t work and the extraction - ejection sequence was
entirely too touchy. The US government bought and fielded thousands
of M16s and then set about working out the bugs. Much improved, the
basic design is still in the hands of US servicemen.

The development of US armored fighting vehicles in that early 1960s
period was certainly marked by heady ambition, innovation and
decidedly mixed results. The M114, a novel scout vehicle rising from
a blank sheet and produced by GM at the Cleveland Tank Plant, was
soon considered marginal and destined for replacement. The new M551
armored reconnaissance / airborne assault vehicle program went to
the same major defense contractor.
While the automotive problems eventually were solved, the troubled
152mm gun - launcher was always a problem and clearly a wrong turn
in US weapons thinking. It was a part of the doomed MBT 70
developmental effort and the M60A2 in its limited fielding. A
Sheridan with some variety of more conventional cannon would have
been a very interesting vehicle. By the time any serious thought
would have been given to this, however, the next generation was well
down the developmental path and M2 - M3 ended any further need for
pursuing a new light tank or extensive remanufacture of the M551.
Lasting well past the micro fleet at Fort Bragg, the long lived
Sheridan program continued at the NTC, even if only a fraction of
its former self and helped train the tens of thousands of US
servicemen who twice won decisively in the desert war they had so
long rehearsed.

What wonderful twists to the Sheridan story; early on fitted with
the Army’s first widespread laser rangefinder, the M551 lived long
at the NTC dueling with MILES laser light against visiting
battalions in the California sun. The design requirement specified
that it be able to swim, we can find no record that it ever did this
in a combat theater. The number of Sheridans destroyed in Vietnam
probably is equal to the number written off in parachute accidents
at Fort Bragg. Its combat record was built in the jungles and rice
paddies of Vietnam in a role it was never designed to play and
decades later, it was key in training a new generation of officers
and men in every nuance of desert warfare. If Waterloo was first won
on the playing fields of Eaton, then at the NTC, in the dust and
heat of the high desert, the Army learned to fulfill former Chief of
Staff Collin Powell’s statement that in part, "...we do deserts" and
a very important aspect of this was the realism in threat vehicle
array that the M551 Sheridan VISMODs provided. From Vietnam to
Germany to the United States, through the decades and across the
continents, the Sheridan is recalled by thousands of troopers, each
with their lasting memories, good and bad.
There probably are surprisingly few Sheridans left. The fleet has
already been depleted by foreign sales, REEFEX projects, the
smelters oven and the coda of down range target details. Those on
static display range from well kept monuments to sad reminders of
past glory. Built in Cleveland, they are scattered now to their
fates. The guys who assembled them are now long retired, the factory
is closed, configured as a convention center, it now features an
indoor Ferris Wheel.

At Fort Knox, along with the Patton Museum and the static display of
both US and foreign tanks, a "living museum" of running vintage
tanks is maintained. Periodically, they are taken out on a road
march for the entertainment of the crowds; the crews wear uniforms
appropriate to the period of their tank. Tankers of all ages, kids
and wives line up for the show. In the near future, as that mixed
column of Shermans and M48s snakes by, towards the end, we hope they
add a Sheridan. With so many just coming out of the inventory, it
would be a shame to not keep at least one in full running order.
In that crowd, standing roadside on a hot 4th of July, an older
veteran shepherding grand children might catch sight of this last
runner from the fleet of 1662 and, as so often an old song or half
forgotten image can suddenly transport you decades to the past in an
instant, this Sheridan would be the catalyst for a cascade of
memories. In that instant he would hold his breath and then recall
with vivid detail, all the facts, the sights and the very feel of
days so far past and then exclaim under his breath to no one in
particular, "the Ho Bo woods in 1970 ... Jimmy, Gunner and me ..."
and for another slightly younger veteran further along in the
crowd,"... so many road marches to Camp Wollbach ... and then Range
80 at Graf ..." and further along still in the crowd, an NCO at a
professional development class, "... look at that, just like at
‘planet Irwin‘ ..." as this last running Sheridan goes by.

Under all the paint and through all the years, if one could find the
first bumper number of this particular Sheridan and talk to the crew
that proudly and hesitantly took possession of the tank, as they
stripped away the manufacturer and depot pack, perhaps it had been
initially assigned to some Troop L in the regimental cavalry. On
that day, that first crew held a meeting, half joking and half
solemn, maybe in Vietnam, maybe in Germany or maybe at Fort Bliss
and discussed a gun barrel name. When they walked back to their
billet that night, in the setting sun, on the 152mm cannon barrel,
still shining as wet paint, it read "Lucky One".

At Fort Knox, this Sheridan is under restoration. We hope it
will be a runner. --Neil Baumgardner
