Description Approximately 148,000 soldiers from the United States, 45,000 British soldiers, 2,000 Australian soldiers, 1300 Spanish soldiers and 194 Polish soldiers from the special forces unit GROM were sent to Kuwait for the invasion. The invasion force was also supported by Iraqi Kurdish militia troops, estimated to number upwards of 70,000. In the latter stages of the invasion, 620 troops of the Iraqi National Congress opposition group were deployed to southern Iraq.
A U.S. Central Command, Combined Forces Air Component Commander report, indicated that, as of 30 April 2003, there were a total of 466,985 U.S. personnel deployed for Operation Iraqi Freedom. This included USAF, 54,955; USAF Reserve, 2,084; Air National Guard, 7,207; USMC, 74,405; USMC Reserve, 9,501; USN, 61,296 (681 are members of the U.S. Coast Guard); USN Reserve, 2,056; and US Army, 233,342; US Army Reserve, 10,683; and Army National Guard, 8,866.
Plans for opening a second front in the north were severely hampered when Turkey refused the use of its territory for such purposes. In response to Turkey's decision, the United States dropped several thousand paratroopers from the 173rd Airborne Brigade into northern Iraq, a number significantly less than the 15,000-strong 4th Infantry Division that the U.S. originally planned to use for opening the northern front.
The invasion was preceded by an air strike on the Presidential Palace in Baghdad on 19 March 2003. The following day, coalition forces launched an incursion into Basra Province from their massing point close to the Iraqi-Kuwaiti border. While the special forces launched an amphibious assault from the Persian Gulf to secure Basra and the surrounding petroleum fields, the main invasion army moved into southern Iraq, occupying the region and engaging in the Battle of Nasiriyah on 23 March. Massive air strikes across the country and against Iraqi command and control threw the defending army into chaos and prevented an effective resistance. On 26 March, the 173rd Airborne Brigade was airdropped near the northern city of Kirkuk, where they joined forces with Kurdish rebels and fought several actions against the Iraqi army to secure the northern part of the country.
The main body of coalition forces continued their drive into the heart of Iraq and met with little resistance. Most of the Iraqi military was quickly defeated and Baghdad was occupied on 9 April. Other operations occurred against pockets of the Iraqi army including the capture and occupation of Kirkuk on 10 April, and the attack and capture of Tikrit on 15 April. Iraqi President Saddam Hussein and the central leadership went into hiding as the coalition forces completed the occupation of the country.
