Wire reports out of London say the U.S. Navy is shipping tanks and heavy armor to the Middle East/Persian Gulf region, using chartered commercial cargo ships. One ship just set sail from a southeastern U.S. port, the report said. According to Reuters, the latest shipment was the third one in a month, and it comes as the United States builds its case for a military invasion of Iraq. Military analysts say the shipping of tanks and other military supplies is similar to what happened in the run up to the 1991 Persian Gulf War, the report said.
