The D-Ration was a revolutionary feat of science that changed the way military chocolate was used throughout World War 2 (WW2).
Wars are usually the birth of rapid technological development due to the increased demand for a lead in the war. Chocolate had many uses throughout War time. Some of these uses include being used a disguise weapon to assist in the attempted assassination of Winston Churchill. Another thought is that chocolate was used as a medicinal supplement to boost morale and soothe various medical problems. These chocolate bars were obviously used as an emergency energy source. The last use, particularly used with the D-Ration, is for throwing the bars at unruly ARVN's who got to close to the tanks during a parade through the streets. ARVN's are members of the Army of the Republic of Viet Nam.
