About 200 combat capable Marines in Sigonella, Italy, and Moron, Spain, have been told to be ready to be airborne within 60 minutes of getting orders to deploy, according to two administration officials.

The units have several V-22 tilt-rotor aircraft that would carry troops and infantry weapons to Egypt to protect the U.S. Embassy and American government personnel and citizens if violence broke out against Americans.

The planned demonstrations are aimed against the Egyptian government.

The officials both emphasized this is contingency planning in advance of the expected demonstrations to ensure American military assets, including rescue forces, can act if needed. In the event Americans had to be evacuated from Egypt and could not get to the airport due to the unrest, there are about 2,000 additional Marines on board three Navy warships in the Red Sea, officials said.
