3 oxidizer, with 46.5% aniline, 46.5% furfuryl alcohol and 7% hydrazine as fuel.[9][10][11][12]
Guidance for the Corporal consisted of a complex system of internal and ground guidance. During the initial launch phase,
A Corporal battalion was composed of 250 men requiring 35 vehicles to deploy and took nine hours to set up the missile to fire once the launch position had been reached.[4]: 125 Corporal missile battalions in Europe were highly mobile, considering the large number of support vehicles and personnel required to support the transportation, checkout, and launch of this liquid-fueled nuclear-tipped (or conventional HE or chemical) missile. In Germany, frequent unannounced 'Alerts' were performed—necessitating assembling all personnel and moving vehicles and missiles to a pre-assigned assembly point. From there the battalion would move to a launch site—usually somewhere in a remote forest—set up the missile on its launcher and go through a detailed checkout of the various systems. This was not a trivial operation as these electronic systems were largely vacuum tubes. A mock firing would be performed and the entire battalion would be gone as soon as possible in order to not be a target of counter-battery fire.
For what was the first nuclear armed missile the Corporal I was significantly unreliable and inaccurate. The continuing development of the Corporal weapon system led rapidly to the development of the Corporal II. This was initiated while the Corporal I was still under development. Though Corporal I was deemed operable many shortcomings in both the missile and ground equipment tactical usability had become obvious during development.[16] Engineer-User trials had shown that the primary reason for mechanical and electrical causes arose because the systems of the Corporal I were too delicate.[4]: 121 Problems detected in the E-U trials were addressed in the Corporal II. The Type II Corporal was subsequently improved in the Corporal IIa and IIb (M2A1) versions. The first Corporal II prototype was flown on October 8, 1953. The first complete Type II system was delivered in February 1955,[17] The Type II Corporal greatly improved the accuracy and reliability of the missile system. When compared to other early missiles the final production Corporal II was reasonably accurate.[18][19][20] Still the aggregate accuracy of all Type IIs with a CEP (Circular Error Probable) of 350 meters which was still short of the desired 300 meters.[17] The role of JPL was greatly reduced in 1955–56.[21]
The deficiencies of the Corporal II led to the design and development of Corporal III. The objectives of Corporal III were to produce a much improved weapon system with improved reliability, ground support equipment, and especially ground guidance equipment, to provide the Army with a fully developed weapon.[22] Only small changes to the Corporal IIb missile would be required.[23] In 1956 all research and development work on the Corporal II had been completed.[24] A study at Redstone Arsenal noted that the MGM-29 Sergeant missile system would become available for service in 1963 and that Corporal III equipment should only be procured for additional Corporal units.[25] Though a Type III Corporal was flown in 1957 it was too late for the eternally developing Corporal system.[4]: 121 On May 23, 1957 all work on the Corporal III was ended to conserve funds for Sergeant following defense budget cuts.[26] In 1963 the solid-fueled Sergeant missiles with self-contained inertial guidance systems which was jamming proof, and which took only an hour from occupying the site to launch of the missile, started replacing the Corporal IIb in Europe. By June 1964 the Corporal system was history in American service.[4]: 125 In June 1966 the last Corporal unit, the 27th Guided Weapons Regiment Royal Artillery, retired its Corporals.[4]: 125
Introduction to service
The first three Corporal battalions were activated in March 1952 with an Engineer-User launch program beginning in January 1953.[27] In the same year the Corporal II system was sold to the United Kingdom.[28] The extremely ambitious original goal of the Corporal program was to have 16 battalions of missiles deployed by July 1954. Two batteries of Corporal I had been organized and equipped by July 1954.[27] The 259th Corporal Battalion deployed to Europe in February 1955. It was followed by other units and by 1960 there were six battalions in Germany, two in Italy and four in the United States.[29] Live-fire training for Germany-based US forces took place at Fort Bliss but later the British Royal Artillery Guided Weapons Range on the Scottish island of South Uist in the Outer Hebrides was used. Missiles were fired toward designated target coordinates in the Atlantic Ocean. Radar on Hirta (the main island of the St Kilda archipelago of Scotland) identified missile landing points. Frequently, Soviet spy ship 'fishing trawlers' would intrude into the target area. The UK adoption of the Corporal resulted in the islet of Rockall being incorporated into the United Kingdom in 1955, the last addition to the UK, to prevent its use by Soviet observers: the UK Minister of Defence Harold Macmillan was concerned that, were they to do so, the Soviets might discover how to jam Corporal guidance and tracking radio signals.[30]

Toys
A version of the Corporal was made as a die-cast toy by manufacturers such as Corgi and Dinky. The Corgi Corporal, marketed to children as "the rocket you can launch", was timed to coincide with the British test firing in 1959.
A 1/40 scale plastic model kit of the Corporal missile with its mobile transporter was produced in the late 1950s and was reissued by Revell-Monogram in 2009.
A 1/48 scale plastic model kit of the Corporal missile with its launcher was produced in 1959 by Hawk and was reissued in 1969 in a glow in the dark version.
