Part 1: The Light Tank, a Valid
Concept
US armored vehicle evolution from the end of World War II to the
present day was a complicated process and to be too brief is to miss
the key detail that builds the story. On the one hand, there is a
seemingly straightforward progression from the M47 to the M48 to the
M60 and M60A1 series to the M60 A3 and finally an evolutionary jump
to the M1. There was always a parallel evolutionary path, heavy
tanks funded then canceled (M103), light tanks proven and abandoned
(M24 and M41), experiments and joint projects to "break the old
design molds" (MBT 70), projects that were disastrous (M60A2) and
production models based on the intersection of new design, new
weapons technology and new war fighting doctrine (M551). Viewed as a
whole, it is a fascinating story of how industry, politics, Generals
and Senators always vie, compete and compromise in the life cycle of
major combat system procurement. The troopers in the squadrons and
battalions held their collective breath and waited for the next ...
big .... thing.

This is 1951, either just before or
after the move to Bad Kissingen. The tank company has the M26
Pershing tank. The guys have good uniform discipline in the field.

Looking out my window towards the
shops, a good side view of the M24 Chaffee. The recon companies had
these light tanks, three per platoon, nine per company. They were
OK.

Often, the argument in the 1950s and early 1960s came down to a
single question: were the needs of the Army best met with a single
medium tank or some combination of light, medium and heavy models?
From the middle of World War II through the early 1960s, generals,
politicians, designers and manufactures passionately argued the
issue.
For a few years, armor development was biased toward one faction,
then, like a pendulum, it would swing towards the counter argument.
Sometimes a compromise was made that pleased many and disappointed
most. World War II experiences fueled arguments for both sides. Had
not vast fleets of the medium and hardy M4 Sherman tank proven the
key ingredient to victory?? Had not the last years of the war proven
that the heavy German tanks, if mass produced, could only be
countered by a US heavy tank?? Wasn't the M24 light tank an ideal
companion to the infantry and scouts?? Hadn't too many different
tanks become a burden for trainers and logisticians?? They argued
back and forth.

Now sometimes they ended up like
this! An M24 that ended up on its side when the trail gave way at
Wildflecken. No one hurt, good thing!

The war in Korea only further complicated the issue. It was not good
tank country but there were some stiff fights. Chinese and North
Korean T34s swept through the M24 light tanks and were stopped by
the medium-heavy M26 US Pershings. The infantry however, argued that
the M24 or some improved model was necessary for the urban fighting
in Korean cities and towns. Clearly, the last of the M4 Shermans had
to go but what would the new armor force look like and as always,
the fear of war in Europe held everyone's attention. The Soviets
seemed to roll out new and potentially dangerous tanks at each May
Day parade.

An M47 on the mini tank range at
Reiterswiesen. The tank was similar in design to the M41 light tank,
the key recognition features in the fotos are the M47 has turret
blisters for the range finder and the M 47 has six road wheels.

In Bad Kissingen, the newly arrived reconnaissance squadron was an
early recipient of each new US tank as fielding went forward for 7th
Army units. Our contacts from the early 1950s clearly recall the
recon companies staffed with the M24 and the tank company with the
M26. 1952-1953 must have been a hectic year on the ranges and
training areas, both old systems disappear, replaced respectively by
the M41 and M47 tanks. Troopers recalled the M24 Chaffee as "light
but hardy, a good runner", but the M41 was a clearly superior
vehicle.
Carried forward by the momentum and funding of tank development from
WWII, the M41 light tank was ready for fielding too late for Korea
but certainly on time for Europe. It was intended to be the
companion "light" tank to the M26 and later M47 then M48
"medium-heavy" tanks in the inventory. The Cadillac Motor Car
Division of General Motors was the prime contractor and over 3700
units were produced at the Cleveland Tank Plant. The new tank
featured some of the innovations the Army had demanded, a fully
powered turret the primary step forward, the potential to experiment
with a semi automated loader and improved optic sights. The
engine-transmission-final drive layout became the platform that,
much modified, drove US tanks through the M60 series. As a
compromise, the Army agreed to accept the vehicle before all the
design requirements were met.

The M4 and the M26 tank seen in a
Detroit Tank Plant photo. In the opening days of the Cold War, the
M26 was redesignated as the M46 following a set of improvements,
and was the main medium - heavy battle tank available to US
forces.

The M41 enjoyed a long life with
allied nations. Seen in Fulda, members of the new German Bundeswehr
receive training at Down Barracks on their freshly issued M41
tanks. Fifteen years later, a South Vietnamese tanker with his
refurbished M41.

At about 26 tons combat weight and a crew of four, it was a success
with the troops. The initial 76 mm cannon was considered acceptable,
the fleet recycled back to the factory at least once during the
operational life with the Army for a series of improvements, the top
speed was listed as 45 mph. The problems of the auto loader were
never satisfactorily worked out and that modification never went
forward. For the infantry and cavalry units, the M41 was fast,
maneuverable and reliable although it consumed fuel at a frightening
rate. It seemed as though those who had argued for an armored force
mix calling for both light and medium tanks were correct.

An M41 is backed into a position in
this 1954 14th ACR unit yearbook image. Interestingly, the yearbook
featured very few photos of the M41. Almost all the tank images were
of the M47.

As a testimony to this design, beyond the production runs to honor
US government contracts, the Cleveland Tank Plant produced several
thousand additional copies for foreign sales. The armor force of the
new West German Army, the Bundeswehr, was first built with M41s and
the South Vietnamese Army followed suite some years later. M41s to
this day, much modified and improved, can be found in service in
several foreign countries. This tank kept thousands of employees of
GM's Cleveland Defense Plant in steady work for over fifteen years.
The troopers held it in high regard.

In the 2nd battalion part of the
1954 yearbook, an imaged titled " crews prep for gunnery exercise ",
shows M41s on the firing line.

A production image from Hunnicutt's
great book shows the clean, clear lines of the M41. It had a short
operational life with the Army but lived for decades around the
world with other forces.
