There was a debate at the beginning of the Korean War about whether to provide daily beer rations for troops. Temperance groups, of course, were against it but the Schlitz and Blatz breweries offered to provide 1.2 million free cans and bottles of beer to the war zone troops. A member of Congress from Milwaukee argued that a beer had no more alcohol content than "a good pudding" and could be a life saver in areas where no potable water was available. Gen. MacArthur also favored a daily beer ration. Eventually Congress approved the beer ration, provided that the beer contained no more than 3.2% alcohol. The first shipment of free beer arrived on Christmas Day 1950. Empty beer cans ultimately served another purpose; it was discovered that hand grenades fit perfectly inside empty beer cans, so the cans were used to safely transport 25,000 unused hand grenades at the end of the war.
