WWII US ARMY TANK DESTROYER STERLING RING WW2

Beautifully enameled WWII US Army Tank Destroyer ring in Sterling and is maker maker to Grouse Co. The rings depict two Federal Eagles, one to each side with a beautifully enameled center piece showing the Tank Destroyer insignia to the center showing no signs of damage. The ring is roughly a size 9. World War II Dedicated anti-tank vehicles made their first major appearance in the Second World War as combatants developed effective armored vehicles and tactics. Some were little more than stopgap solutions, mounting an anti-tank gun on a tracked vehicle to give mobility, while others were more sophisticated designs. An example of the development of tank destroyer technology throughout the war are the Marder III and Jagdpanzer 38 vehicle, that were very different in spite of being based on the same chassis: Marder was straightforwardly an anti-tank gun on tracks whereas the Jagdpanzer 38 traded some firepower (its Pak 39, designed to operate within the confines of a fully armored fighting compartment, fires the same projectiles from a reduced propellant charge compared to Marder's Pak 40) for better armor protection and ease of concealment on the battlefield. Except for most American designs, tank destroyers were all turretless and had fixed or casemate superstructures. When a tank destroyer was used against enemy tanks from a defensive position such as by ambush, the common lack of a rotating turret was not particularly critical, while the lower silhouette was highly desirable. The turretless design allowed accommodation of a more powerful gun, typically a dedicated anti-tank gun (in lieu of a regular tank's general-purpose main gun that fired both anti-tank and high explosive ammunition) that had a longer barrel than could be mounted in a turreted tank on the same chassis. The lack of a turret increased the vehicle's internal volume, allowing for increased ammunition stowage and crew comfort. Eliminating the turret let the vehicle carry thicker armor, and also let this armour be concentrated in the hull. Sometimes there was no armored roof (only a weather cover) to keep the overall weight down to the limit that the chassis could bear. The absence of a turret meant that tank destroyers could be manufactured significantly cheaper, faster, and more easily than the tanks on which they were based, and they found particular favor when production resources were lacking. After hard lessons early in the war, machine guns were mounted for use against infantry, but the limited traverse of the mounting meant that they were still less effective than those used on turreted tanks. United States U.S. Army and counterpart British designs were very different in conception. U.S. doctrine was based, in light of the fall of France, on the perceived need to defeat German blitzkrieg tactics, and U.S. units expected to face large numbers of German tanks, attacking on relatively narrow fronts. These were expected to break through a thin screen of anti-tank guns, hence the decision that the main anti-tank units—the Tank Destroyer (TD) battalions—should be concentrated and very mobile. In practice, such German attacks rarely happened. Throughout the war, only one battalion ever fought in an engagement like that originally envisaged (the 601st, at the Battle of El Guettar). The Tank Destroyer Command eventually numbered over 100,000 men and 80 battalions each equipped with 36 self-propelled tank destroyers or towed guns. Only a few shots were expected to be fired from any firing position. Strong reconnaissance elements were provided so that TDs could use pre-arranged firing positions to best advantage. Flanking fire by TDs was emphasized, both to penetrate thinner enemy side armor, and to reduce the likelihood of accurate enemy return fire. All American tank destroyers were officially known by exactly the same collective term used for American self-propelled artillery ordnance, gun motor carriage. The designs were intended to be very mobile and heavily armed. Most of the tank-hull based designs used special open-topped turrets of a differing design to the original tank it was based on, which was meant to both save weight and to accommodate a larger gun. The earliest expedient design was an M3 Half-track mounting an M1897 75 mm gun in a limited-traverse mount, and called the 75 mm Gun Motor Carriage M3. Another, considerably less successful, early design mounted a 37-mm anti-tank gun in the bed of a Dodge 3/4-ton truck—the 37-mm GMC M6. By far the most common US design, and the first that was fully tracked and turreted (which became the American hallmark of World War II "tank destroyer" design) was the 3in Gun Motor Carriage M10, later supplemented by the 90 mm Gun Motor Carriage M36—both based on the M4 Sherman hull and powertrain—and the 76 mm Gun Motor Carriage M18 (Hellcat), based on a unique hull and powertrain design, with a slight visual resemblance to what was used for the later M24 Chaffee light tank. The M18 came closest to the US ideal; the vehicle was very fast, small, and mounted a 76 mm gun in a roofless open turret. The M36 Jackson GMC possessed the only American-origin operational gun that could rival the vaunted 88 mm German anti-tank ordnance, the 90 mm M3 gun, and the M36 remained in service well after World War II. The only dedicated American-origin, casemate hull design fighting vehicle of any type built during the war, that resembled the German and Soviet tank destroyers in hull and general gun mounting design, was the experimental T28 Super Heavy Tank, which mounted a 105 mm T5E1 long-barrel cannon, which had a maximum firing range of 12 miles (20 km), and was originally designed as a self-propelled assault gun to breach Germany's Siegfried Line defenses. Of these tank destroyers, only the 90 mm gun of the M36 proved effective against the frontal armor of Germans' larger armored vehicles at long range. The open top and light armor made these tank destroyers vulnerable to anything greater than small-arms fire. As the number of German tanks encountered by American forces steadily decreased throughout the war, most battalions were split up and assigned to infantry units as supporting arms, fighting as assault guns or being used essentially as tanks. In this sense they were an alternative to the Independent tank battalions that were attached to various Infantry Divisions. The expectation that German tanks would be engaged in mass formation was a failed assumption. In reality, German attacks effectively used combined arms on the ground, fighting cohesively. American tank destroyer battalions comprised three tank destroyer companies supported by nine security sections. The single-purpose tactics of the tank destroyer battalion failed to account for non-tank threats.
