He completed Airborne and Ranger schools prior to receiving his initial assignment in Germany with the 3rd Infantry Division (Mechanized) as a rifle platoon leader and later as a scout platoon leader and company executive officer in 1st Battalion, 7th Infantry.

Following this assignment and attendance at the Infantry Officer Advanced Course, he was assigned to the 82nd Airborne Division at Fort Bragg, North Carolina, where he commanded the Combat Support Company, 2nd Battalion (Airborne), 508th Infantry and served as the Assistant S-3 (Operations) for 1st Brigade.

He subsequently served as Chief of Staff of US Central Command at MacDill AFB in Tampa, Florida, from September 2005 until October 2006.

Commanding General of Multi-National Corps – Iraq

On December 8, 2006, Austin was promoted to lieutenant general and assumed command of XVIII Airborne Corps, Fort Bragg, North Carolina. In February 2008, Austin became the second highest ranking commander in Iraq, taking command of the Multi-National CorpsIraq (MNC-I). As commander of MNC-I, he directed the operations of approximately 152,000 joint and coalition forces across all sectors of Iraq. He was the first African American general officer to lead a corps-sized element in combat. Austin assumed the mission during the period when the Surge forces were drawing down. He expertly oversaw the responsible transition of forces out of the country while ensuring that progress continued on the ground.

Austin handed over command of XVIII Corps to become Director of the Joint Staff in August 2009. This promotion came at the direction of Admiral Michael Mullen, then chairman of the Joint Chiefs of Staff. Austin credited the appointment as having jumpstarted his later career, saying: "People who might not have known Lloyd Austin began to know him."

Commanding General of US Forces – Iraq On September 1, 2010, at a ceremony at Al-Faw Palace in Baghdad, Austin was promoted to the rank of general, becoming the Army's 200th four-star general officer and the sixth African American in the U.S. Army to achieve the top rank. He subsequently assumed the role of Commanding General (CG) of United States Forces – Iraq (USF-I), becoming the first African American in history to command an entire theater of war. He was preceded in the role by General Ray Odierno. As CG, USF-I, Austin was the senior military commander in charge of all US and remaining coalition forces in Iraq. Their mission was to advise, train, assist, and equip the Iraqi Armed Forces and the security agencies part of the Ministry of the Interior. As commander, Austin requested an additional troop presence in Iraq from 14,000 to 18,000.

Austin oversaw the transition from Operation Iraqi Freedom and combat operations to Operation New Dawn and stability operations focused on advising, assisting, and training the ISF. He was extensively involved in the internal U.S. discussions and then negotiations with the Iraqi Government leading up to the signing of the Strategic Partnership Agreement. Opposing total U.S. withdrawal, Austin preferred that the U.S. maintain about 10,000 troops in Iraq after 2011 and he approved staff planning for up to 20,000 remaining troops.

In the absence of a new Status of Forces Agreement, President Barack Obama made the decision to retrograde all U.S. forces out of Iraq by the end of 2011. Austin oversaw the entire operation, concurrently planning and executing the orderly drawdown and redeployment of approximately 50,000 service members. The U.S. command in Iraq formally cased its colors on December 15, 2011, at a reduced-sized BIAP complex, and Austin's speech there cited his division's seizure of the airport over eight years beforehand. Austin, along with other members of the USF-I staff, departed Iraq on December 18, 2011.

Army Vice Chief of Staff In December 2011, Austin was nominated to become Vice Chief of Staff of the United States Army (VCSA). He took office on January 31, 2012. As VCSA, he managed the day-to-day administration of the Army's budget and headquarters staff. Under his direction, the Army took steps to reduce the incidence of suicide in the ranks. He also spearheaded the Army's efforts to increase awareness and improve treatment options for the "invisible wounds" of war, namely traumatic brain injuries and post-traumatic stress.

United States Central Command Austin became the commander of CENTCOM on March 22, 2013, after being nominated by President Obama in late 2012. Austin was preceded as CENTCOM commander by General James Mattis, whom Austin would later succeed as secretary of defense. In his capacity as CENTCOM Commander, General Austin oversaw all U.S. troops deployed and major U.S. military operations around the area of Middle-East and Central and South Asia. The area consisted of 20 countries including Iraq, Syria, Yemen, Afghanistan, Egypt and Lebanon.

Austin directed the activities of four service component commands, one subordinate unified command (U.S. Forces-Afghanistan/Resolute Support Mission), two major subordinate multi-service commands, and several temporary task forces actively engaged in military operations. Austin oversaw more than 150,000 American and Coalition forces involved in operations throughout the region.

During his tenure, Austin routinely advised the president, the secretary of defense, and other national-level leadership on challenges afflicting the CENTCOM region, and directed U.S. and allied military response to multiple crises and operations. These included the explosive crisis and transition of power in Egypt (2013–14); the resurgence of Al Qaeda's affiliate in the Arabian Peninsula; the Huthi-led insurgency against the Hadi government and the civil war in Yemen; continued support for the operations in Afghanistan against Al Qaeda and other extremist groups; malign activity by Iran's Revolutionary Guard Corps-Qods Forces; and the rise of the Islamic State of Iraq and the Levant (ISIL) in Iraq and Syria (also known as the Islamic State of Iraq and Syria (ISIS)).

As commander, after ISIL seized control of Mosul in June 2014, Austin oversaw the development and execution of the coalition military campaign plan to counter ISIL in Iraq and Syria, named Combined Joint Task Force – Operation Inherent Resolve (CJTF-OIR). At its peak, ISIL (also referred to as Daesh) controlled nearly 110,000 square kilometers of territory, including major cities in both Iraq and Syria, and attracted more than 40,000 foreign terrorist fighters. As of October 2014, Austin argued that the U.S. military's primary focus in operations against ISIL should be Iraq. The military campaign to counter ISIL consisted of multiple elements occurring simultaneously or near-simultaneously, including: 1) employing a coalition effort in Iraq to halt the advance of ISIL and to enable the Iraqis to regain their territory and reestablish control over their borders; 2) containing ISIL, in part by ensuring coalition partners have the capacity to secure their sovereign borders; 3) enabling the moderate Syrian opposition forces through a coalition-led train and equip program; and 4) eliminating ungoverned spaces out of which ISIL and other terrorist groups were able to operate.

In its first year, CJTF-OIR conducted over 8,000 airstrikes against ISIL targets in Iraq and Syria. Between 2014 and 2017, ISIL lost 95 percent of the territory they once controlled. By July 2017, Mosul was once again under the control of the Iraqi government, and by December 2017, ISIL had lost all control of territory in Iraq.
