Lieutenant General (Ret.) Michael H. “Mike” Shields built a distinguished 34 year career in the U.S. Army before bringing his operational insight and strategic leadership to CACI. Today, he serves as senior vice president of Advanced Technology for Mission Adoption, helping accelerate next generation technologies that support the nation’s most critical missions.

Since joining the Army in 1985, Shields has served in a wide range of challenging command assignments to include the 3rd Battalion, 504th Parachute Infantry Regiment and most notably the 172nd Stryker Brigade Combat Team in Iraq, which received the Valorous Unit Award for extraordinary heroism in military operations against an armed enemy. The 172nd SBCT was extended during redeployment and served one of the longest combat tours of the war. He later went on to serve as commanding general, United States Army Alaska.

Shields has served in several key strategy and policy positions within the Joint Staff including assistant deputy director for European NATO Russian and African Policy and director of the National Joint Operations and Intelligence Center in the NMCC. In 2010, he was assigned as the deputy director for Operations and Intelligence for the Joint Improvised Explosive Device Defeat Organization. He returned from Afghanistan in 2012 to serve on the Joint Staff as the director of the Pakistan Afghanistan Coordination Cell. His final role in the Department of War was as director of the Joint Improvised Threat Defeat Organization (Defense Threat Reduction Agency).

Throughout his military career, Shields worked extensively in joint environments and high risk missions, gaining deep expertise in threat analysis, rapid innovation, and operational integration. These experiences shaped his understanding of how emerging technologies can be fielded effectively to support warfighters in dynamic environments.

Shields joined CACI in May 2019. In his role on the strategy team, he supports strategic planning to ensure advanced technologies are aligned to customer mission needs and are successfully integrated into operational use.

Shields was drawn by CACI’s strong heritage supporting intelligence community and defense missions and its growing portfolio of mission critical technologies. He recognized CACI’s commitment to developing advanced capabilities that directly support warfighters and national security priorities, an alignment that allowed him to continue his service in a new capacity.
