STAGE 1

A massive attack on Iraq's air defenses, Frog and Scud missile sites, and command centers.

The objective: Eliminate missiles threatening Israel and multinational forces. Destroy bunkers from which Saddam's field officers -- and perhaps Saddam himself -- issue orders. Win control of the skies so that allied air forces can operate with relative impunity.

STAGE 2

An offensive against rail lines, roads, ammunition and fuel depots, and other logistical targets.

The objective: Isolate Saddam's forces in Kuwait and hamper resupply efforts. STAGE 3

A concentrated attack on Iraq's ground forces, including elite Republican Guard units in southern Iraq and Kuwait.

The objective: Weaken opposition to U.S. ground forces as much as possible. STAGE 4

A ground attack by the U.S.-led multinational force.

The objective: Eject Iraqi forces from Kuwait. KEY WEAPONS IN THE ARSENAL

Tomahawk: Rocket-launched, jet-propelled missile is fired from U.S. ships or submarines and guided to target by on-board computer.

AWACS: Airborne warning and control system aircraft provide surveillance over a wide area. The "dome" on top of the planes contains radar equipment.

B-52: Large, long-range bomber can carpet-bomb targets or launch cruise missiles from great distances.

F-117A fighter: Advanced, single-seat fighter uses "stealth" technology to remain nearly invisible to enemy radar. Key weapon for Stage 1.

F-15: Among the Pentagon's most sophisticated combat aircraft, F-15s can be used as either fighter-interceptors (in dogfights) or as fighter-bombers.

F-16: Fast, maneuverable air-combat fighter.

F-111: Long-range bomber was used in April 1986 attack on Libya.

F-4G Wild Weasel: Fighter packed with electronic equipment can destroy or suppress enemy radar systems.

Harrier AV-8B: Single-seat attack aircraft flown by Marines can take off vertically.

AH-64 Apache: Advanced attack helicopter used against enemy tanks.

A-6E Intruder: Carrier-based attack bomber can be used for air support and missions deep inside enemy territory.

A-10 Thunderbolt: Slow, low-flying attck aircraft is used primarily to destroy tanks.
