M10 Wolverine

CountryUnited States
Primary RoleTank Destroyer


ww2dbaseThe German Army doctrine of concentrating tanks to rapidly penetrate enemy defensive lines led to the US Army's request for a new weapon dedicated to counter such offensives. In Jun 1942, prototype tank destroyer T35E1 was finalized into the 3-inch Gun Motor Carriage M10 and was ordered into full production. A variant design was developed for British use, which was designated as (Gun) 3 inch Self Propelled Wolverine by the British Army. They were built upon the M4 Sherman medium tank chassis and had open-topped turrets, and the 3-inch M7 guns were rated to penetrate 3 inches of armor at the distance of 1,000 yards at 30 degrees from vertical. Some of the British Wolverine vehicles were later upgraded with Ordnance QF 17 pounder Mark V guns (and redesignated 17pdr SP Achilles), which improved armor penetration capabilities. M10 tank destroyers first saw action in 1943 in Tunisia, where their guns could penetrate the armor of any Axis armored vehicle in North Africa. It was not until the Normandy campaign in mid-1944 when they began encountering tanks, namely Tiger and Panther tanks, which were immune to the 3-inch and 17-pounder guns. Additionally, by this time the US Army generals were beginning to see that the massed tank assaults that they studied in 1940 which led to the M10 design no longer took place with significant frequency, thus concentrating numbers of M10 tank destroyers in the rear to counter possible enemy tank assaults was actually not effective. Thus, some M10 tank destroyers began to be assigned to front line infantry units for use as infantry support guns, sometimes fighting alongside their successors 90mm Gun Motor Carriage M36. A number of them were also used in the Pacific War where crews reported that the open-top design made them vulnerable to tactics employed by Japanese troops, which brought the enemy much closer to the vehicles. Another complaint, made by M10 crews in all theaters, was that the unpowered turrets required hand cranks to turn, which was very slow especially in combat conditions.

ww2dbaseAbout 54 M10 tank destroyers made their way to the Soviet Union during the war, while a few of them were also used by the Free French. After the war in 1949, 17 (1 prototype and 16 production) M10 tank destroyers without working guns, with thicker armor, and each with an additional bow gun port were sold to the Republic of China; the Chinese troops equipped them with captured Japanese 150-millimeter infantry howitzers just prior to withdrawing to Taiwan.

The M-10 Wolverine first saw service,at the end of 1942 in North Africa. It was armed
with the 3 inch M-7 cannon and the .50 cal
machine gun.
Many were supplied to the British and Free
French Forces, the main weakness, of most
U.S. tank destroyers, was the open turret,
that left the crew exposed to enemy fire
and air attack, so armored roofs were often
improvised in the field.

Another U.S. tank destroyer was the M-18
Hellcat,this vehicle had the fastest top speed of any tank destroyer over 50 mph
on the road and 25 mph cross-country.
The Hellcat used the tactic of shoot & scoot
the vehicle was fast enough to get into a
firing position,or break-off when necessary
and fall back to another position.
M-18 units achieved astonishing numbers of
tank and other armored vehicle kills.
During one battle, the 630th Tank Destroyer
Battalion reported knocking out 53 Tigers,
Panthers and 15 StuG III Assault Guns, with
a loss of 17 M-18's. Total production was
2,507 unlike other tank destroyers, the M-18
was powered by a 9-cylinder radial engine.
At the end of W.W.II,all tank destroyer units
were disbanded.
During the post-war years, the U.S. Army continued to use the vehicle in lmited roles.
Surplus M-18's were given or sold to Allied
or Neutral States. Yugoslavia kept them into
the 1990's, the Serb Army used them during
the Yugoslav Wars.
During W.W.II,my late Uncle Raymond De Nomie
served in tank destroyers. I have a patch he gave me, a Black Panther bitting into a tank
He would talk little about his experiences
during the war, he passed away in 1975.
When I told him, I was going to Vietnam in 1967, I could see the tears in his eyes, but
he kept his composure, he gave me a hug and
a handshake,"And told me to be careful" what
more could he say.
After my second tour, and discharge in 1970
I wore my uniform stopping to visit, on my
way home. I could see a look of pride in his
eyes looking at the eight ribbions, for medals won for service,made Sergeant. My two tours of service in Vietnam,showed after all that I had become,an experienced and capable
soldier, who like my Uncle saw war, and it would forever be apart of him.
