South Korea has agreed to buy about 250,000 tons of stockpiled U.S. military munitions, a U.S. Forces Korea spokesman confirmed Tuesday.

South Korea will pay for the munitions, about half of the total War Reserve Stocks for Allies stockpile, by providing about $280 million in services, including "storage, domestic transportation, loading and unloading, and port handling of rejected munitions," according to an e-mail response from USFK spokesman Dave Palmer.

The U.S. Congress passed legislation in 2005 to authorize the transfer, according to Palmer.

The total stockpile is worth about $2.2 billion if bought at today’s prices, according to Palmer.
