Special Forces Open Ground Campaign

U.S. Special Forces have begun the ground phase of America's war against terrorism in Afghanistan, operating in small numbers in southern Afghanistan in support of the CIA's effort in the Taliban heartland, defense officials said yesterday.
The number of U.S. personnel on the ground is just a handful now and is unlikely to ever resemble the large conventional forces assembled in the Persian Gulf War a decade ago, defense officials said. But their presence marks a turning point in only the second week of the conflict, heightening the risk to U.S. forces and underscoring the seriousness of the Bush administration's commitment to prosecuting its war against terrorism.
