Here are the main military components announced so far:
WHO IS THERE ALREADY?
* The bulk of the forces announced for Haiti have not yet arrived but the military expects to have about 1,000 personnel on the ground in Haiti on Monday and thousands more positioned on ships off shore.
* A U.S. Navy aircraft carrier, the USS Carl Vinson, arrived on Friday with 19 helicopters on board. It has three operating rooms, several dozen hospital beds and can produce about 35,000 gallons of drinking water per day. It will be flying airlift missions and delivering more than 30 pallets of relief supplies.
* Air Force special forces were among the first military relief workers to arrive. The Coast Guard has sent four ships and two more are expected to arrive on Friday. The Navy destroyer USS Higgins, with about 320 sailors on board, arrived on Thursday.
MORE THAN 5,000 MARINES, SOLDIERS
* Up to 3,500 soldiers from the U.S. Army's 82nd Airborne Division at Fort Bragg will have been deployed in Haiti by Sunday.
* About 2,200 Marines from the 22nd Marine Expeditionary Unit at Camp Lejeune should arrive by Monday for what initially is expected to be about a 90-day deployment.
* Admiral Mike Mullen, chairman of the Joint Chiefs of Staff, said he has not ruled out sending additional forces to Haiti if required.
AMPHIBIOUS GROUP, FLOATING HOSPITAL
* An amphibious readiness group with three ships -- USS Bataan, USS Fort McHenry and USS Carter Hall -- will take the Marines to Haiti and will arrive by Monday. This group can produce its own purified water.
* The much-anticipated hospital ship, the USNS Comfort, with one of the largest trauma facilities in the United States, will not arrive until around Jan. 22. It has 12 operating rooms and 250 hospital beds, four X-ray units, one CAT scan unit, an invasive angiography suite and two oxygen-producing plants. Comfort also has up to 5,000 units of blood on board.
* Two additional ships, the USS Underwood and USS Normandy, with 400 and 250 personnel, are expected to arrive on Jan. 16. (Reporting by Phil Stewart; Editing by John O'Callaghan)
