Camp Mackall, North Carolina, now a training center for Army Special Operations Forces, was the headquarters of the U.S. Army Airborne Command during World War II. Several airborne divisions trained there, notably the 11th, 13th, and 17th Airborne. Airborne forces were still in their infancy in World War II, and the United States did all that it could to increase their potency. The Army established the Airborne Test Board at Camp Mackall to evaluate airborne tactics, techniques, and equipment. Sometimes these experiments were unusual. The acquisition of a veteran’s photographs revealed a nearly forgotten experiment at Camp Mackall: the 151st Airborne Tank Company.

Formed at Fort Knox, Kentucky, in May 1943, the 151st Airborne Tank Company was to provide airborne forces with an organic armor capability.1 The unit was not meant to engage enemy tanks, but instead was an attempt to give airborne units at least a semblance of being able to fight off enemy probes with something other than light anti-tank weapons. The M22 tanks of the 151st were to be delivered to the field via gliders or belly-slung under a C-54 cargo aircraft.2 Neither method proved practical. The largest glider in U.S. Army service, the CG-13, was not large enough to accommodate the M22. The tank was eventually abandoned for consideration in combat operations by the U.S. Army.

The 151st was commanded by Captain Felix Hege; four other officers and fifty enlisted men were assigned as cadre. Early members of the 151st joined from various armor units in training around the United States. Private Roger Justesen joined because of the extra incentive pay that the “airborne” tankers received.3 Another 120 enlisted recruits, many from Iowa, served to fill the remaining slots.4 The company was organized into three platoons of five tanks each, a reconnaissance platoon with jeeps and M3 halftracks, and a headquarters platoon of three tanks—a total of eighteen tanks.5 Their M22s arrived about six weeks after the company was formed, and the group trained on ground tactics though the cold Kentucky winter of 1943/1944.6 In the spring of 1944, the unit was transferred to Camp Mackall.

By their nature, airborne units—especially in WWII—were lightly armed. Their mission was to seize and hold an objective until more heavily armed and supported regular Army units arrived. Before this link-up, the greatest threat that an isolated airborne unit could face was an enemy armor force. This possibility was greatly feared in WWII. Although the Japanese were not great proponents of tank warfare and, as such, did not have very capable tanks, the Germans had large and well-trained armor units. Their tank development was years ahead of the Allies.

For much of the war, U.S. airborne forces only had limited means at their disposal to protect against armor attack. Hand-held weapons included various grenades and the Rocket Launcher, M1A1, commonly known as the “Bazooka.” Introduced in 1942, the M1A1 fired an eight-pound M6 2.36-inch rocket that had an effective range of 300 yards. The rocket had a hollow shaped-charge that—under ideal circumstances—could penetrate up to four inches of vertical armor plate. But late in the war, the M1A1 proved relatively ineffective against the thick, angled armor of German heavy tanks.

This was not a failing of the airborne, because the Army had largely ignored anti-tank warfare. Although tanks had been used in WWI, the interwar French, British, and U.S. militaries employed them as infantry support. It wasn’t until 1939, after the German Blitzkrieg in Poland, that the U.S. Army took a 37mm German anti-tank (AT) gun design and reengineered it as the M3. It was fielded in 1940. Still, by doctrine, these AT guns were to support infantry divisions. The fall of France and the Low Countries in 1940 forced the Allies to take notice that tanks employed en masse could punch holes through enemy defenses that were then exploited by following infantry. However, the U.S. stop-gap solution to counter this was to rapidly equip their formations with anti-tank guns. The German armor improved throughout the war whereas U.S. counter-measures, improved AT guns, tank destroyers, and better tanks, came slowly. Unfortunately, pre-war thinking and capabilities dominated what was supplied to the Army’s airborne forces.

Airborne units were also equipped with towed anti-tank guns. These, along with a jeep to tow them, were to be delivered to the drop zone via CG-4A Waco gliders (see Troy J. Sacquety’s “The CG-4A Waco Glider”) The standard anti-tank gun in U.S. service at the beginning of the war was the 37mm M3. Its small size meant that it was already obsolete when it entered service and the gun could not effectively engage anything but softskinned vehicles or the smallest of tanks. Although it remained in use in the Pacific throughout the war, its utility in Europe was severely limited by the larger German armor. By 1944, attempts were being made to replace it with the larger British-made 57mm M1 anti-tank gun, although this too was only a stop-gap measure to use a weapons system that had already been developed. The airborne forces needed a new capability.

In 1941, to complement these weapons, several manufacturers were asked by the Army to develop an air-transportable tank. The design submitted by the Marmon-Herrington Corporation of Indianapolis, Indiana, was chosen and designated the T9E1. In U.S. Army nomenclature, it was named the M22, and was known in British parlance as the “Locust.” More than 800 of these tanks were built from April 1943 to February 1944. The M22, crewed by three, was less than thirteen feet long and weighed just under eight tons. In comparison, an M4 Sherman medium tank, crewed by five, was nineteen feet long and weighed thirty-three tons. The M22 was lightly armed with a 37mm M3 as the main gun (a variant of the M3 anti-tank gun) and a .30 caliber machinegun. It carried fifty rounds of 37mm and 2,500 rounds of machinegun ammunition. The strengths of the M22 were speed (35 mph), a low profile that made it a difficult target, and an operational range of over one hundred miles. In reality, the tank was not capable of engaging anything but the lightest of enemy vehicles. Yet it could serve as an effective mobile pill box for infantry protection or assault.7

The problem with the M1A1, M3, and M22 was that, like U.S. anti-tank warfare, they had not kept pace with German armor development. At the time of their design, the main tanks in German service were the Panzerkampfwagen I and Panzerkampfwagen II. Only limited numbers of Panzerkampfwagen IIIs and Panzerkampfwagen IVs were then in use. This rapidly changed. By 1943, an up-gunned and up-armored Panzerkampfwagen IV was the main German battle-tank, and large numbers of Panther and Tiger tanks were entering service. By 1944, the Germans were fielding even heavier tanks and tank destroyers. American anti-tank weapons simply could not compete against these new armor vehicles.

American tanks could do little better. Among the main types of tanks in U.S. service, the M3 “Stuart,” was armed with only a 37mm main gun developed from the M3 anti-tank weapon. It was completely inadequate against any German tank it might meet. The United States needed heavier tanks. Even later in the war, after being fitted with a larger gun, the main American battle tank, the M4 Sherman with a 76mm gun, was no match for the German tanks coming into service.8 Despite being horribly outclassed while it was on the drawing board, operational tests with the M22 continued.

When they arrived at Mackall, the non-glider qualified tankers wore their pants bloused airborne style. This caused quite a stir among the airborne troopers already training at Mackall. “Many an altercation took place.”9 S/SGT Gabriele Sciabarasi, a 151st veteran, later mused, “The airborne didn’t like us and they resented us due to the fact that we weren’t jumpers but bloused our boots and wore the airborne [tab] in town. We got into fights and had bloody noses … nobody got killed … they just had fun, it was a rivalry.”10 Rasbold remembers that Camp Mackall was rustic, had lots of sand, and that “police call” and “pine needles” occupied their time. He remembered that the tar paper barracks were heated with a single pot-belly iron stove, and were so cold that when someone went on leave, the remaining soldiers would inch their bunks that much closer to the stove to savor its heat.11

Most of the unit’s time at Camp Mackall was spent on field exercises. Sciabarasi recalled that other than in town, there was “no intermingling with other troops at Mackall. We were more or less like a secret organization—there was not a lot of publicity on us.” Referring to the British use of airborne tanks in the Normandy Invasion on 6 June 1944, he added, “We were supposed to have been a surprise unit but the English spoiled it.”12 The group mainly exercised apart from the airborne and glider units at Camp Mackall. Occasionally, they would split the company in two and manuever against one another.13

In September 1944, the 151st members received their glider wings for training in the CG-4A Waco. They did not test their methods by using the much larger CG-13 glider, but several members did take orientation flights in the craft.14 In late October 1944—at the same time that the British 1st Airborne Division and the Polish 1st Independent Parachute Brigade of the 1st Allied Airborne Army was being shattered by the Germans in Operation MARKET-GARDEN—twelve 151st members, along with representatives of other airborne units, were sent to Washington DC to demonstrate their potential capabilities.15 Despite the demonstration, the 151st was disbanded around Christmas 1944.16 By this time, it had become self-evident that the M22 was not combat-capable, and the 151st Airborne Tank Company became an unheralded “casualty” of the Germans last-ditch offensive in the Ardennes, Operation Wacht am Rhein (Watch on the Rhine)—popularly known as the Battle of the Bulge. This left the U.S. Army short of combat replacements.

When the 151st broke up, all but two members (who stayed behind to work on the Airborne Test Board) were sent overseas. One of the members who stayed was Sciabarasi, while Justesen and Rasbold were sent to Europe with the 13th Armored Division and XVIII Airborne Corps, respectively. The U.S. Army’s WWII experiments with airborne armor were over.

The remaining tanks were used for training purposes or given to the British, who had a longer history of using airborne tanks.17 The British had the Hamilcar glider, which was capable of carrying a vehicle as heavy as a light tank. Several Tetrarch tanks had even been brought in by Hamilcar glider in the Normandy Invasion, and the British were interested in further combat experiments with airborne tanks. The British landed several Tetrarchs and M22s via Hamilcar gliders in Operation VARSITY, the Allied airborne invasion over the Rhine River on 24 March 1945, but only a few got into action.19 Since Operation VARSITY was the last airborne operation in the European theater, it was the first and only time the M22 saw action in WWII. Remaining examples in the U.S. inventory were given to Allied nations. Several M22s were used, unsuccessfully, by the Egyptians against Israel during the 1948 Arab-Israeli War.
