Military chocolate (United States)

context: en: Logan was pleased with the first small batch of samples. In June 1937, the United States Army ordered 90,000 D ration or "Logan Bars" and field tested them at bases in the Philippines, Panama, on the Texas border, and at other bases throughout the United States. Some of the bars even found their way into the supplies for Admiral Byrd's third Antarctic expedition. These field tests were successful, and the Army began making irregular orders for the bars.

context: en: Military chocolate has been a part of the standard United States military ration since the original Ration D or D ration bar of 1937.  Today, military chocolate is issued to troops as part of basic field rations and sundry packs. Chocolate rations served two purposes: as a morale boost, and as a high-energy, pocket-sized emergency ration. Military chocolate rations are often made in special lots to military specifications for weight, size, and endurance. The majority of chocolate issued to military personnel is produced by the Hershey Company.

context: en: The first emergency chocolate ration bar commissioned by the United States Army was the Ration D, commonly known as the D ration. Army Quartermaster Colonel Paul Logan approached Hershey's Chocolate in April 1937, and met with William Murrie, the company president, and Sam Hinkle, the chief chemist. Milton Hershey was extremely interested in the project when he was informed of the proposal, and the meeting began the first experimental production of the D ration bar.

context: en: The rhetoric of "war rations aligned food consumption with the war in Europe and Asia but also with the vitality of U.S. agriculture and consumerism. While these campaigns aimed to conserve U.S. food surpluses for the purpose of providing food aid to overseas militaries and civilian populations, they also functioned to jettison certain foodstuffs." Production of the D ration bar was discontinued at the end of World War II. However, Hershey's Tropical Bar remained a standard ration for the United States Armed Forces. The Tropical Bar saw action in Korea and Vietnam as an element of the "Sundries" kit (which also contained toiletries), before being declared obsolete.  It briefly returned to use when it was included onboard Apollo 15 in July 1971.

context: en: When provided as an emergency field ration, military chocolate was very different from normal bars. Since its intended use was as an emergency food source, it was formulated so that it would not be a tempting treat that troops might consume before they needed it. Even as attempts to improve the flavor were made, the heat-resistant chocolate bars never received enthusiastic reviews. Emergency ration chocolate bars were made to be high in energy value, easy to carry, and able to withstand high temperatures. Withstanding high temperatures was critical since infantrymen would often be outdoors, sometimes in tropical or desert conditions, with the bars located close to their bodies. These conditions would cause typical chocolate bars to melt within minutes.
