In 2026, U.S. civil-military relations entered an unusual phase when Secretary of Defense Pete Hegseth abruptly removed several top military officials. Most notably, General Randy George, the Army Chief of Staff, was asked to retire immediately, even though he had not completed his term—a rare move during wartime. Alongside him, General David Huddon, who led the Army’s Training and Doctrine Command, and Major General William Green Jr., the Chief of Army Chaplains, were also relieved of their duties. These changes occurred amid heightened tensions between the U.S. and Iran, where rapidly evolving strategic and operational demands prompted the appointment of new leadership. The 2026 removals sparked debate over whether military leaders must fully align with civilian political directives or maintain professional independence as a cornerstone of a non-political military.
Looking slightly back, during President Trump’s administration, civil-military tensions were pronounced. In 2018, James Mattis resigned over disagreements about the withdrawal of U.S. forces from Syria. H.R. McMaster was removed due to foreign policy differences, while John Kelly stepped down over conflicts regarding administrative and immigration policies. Mark Esper was relieved in November 2020 over disagreements regarding the domestic deployment of military forces. After the 2020 election, Craig Faller was reassigned for taking a position contrary to presidential orders, Charles Brown was removed over military advice disagreements on election results, and Christopher Miller was relieved in January 2021 for disputes over defense planning. Mark Milley remained in his position, but political pressures and public protests made his guidance critical for maintaining military stability.
Going further back, the 2010s and earlier decades also saw high-profile removals. General Stanley McChrystal was relieved in 2010 by President Barack Obama for publicly criticizing civilian leadership during the Afghanistan war. In Iraq and Afghanistan, General Ricardo Sanchez was removed following the Abu Ghraib scandal, which raised questions about leadership and accountability.
During the Vietnam War, General William Westmoreland was removed after the Tet Offensive due to strategic criticism and declining public confidence. In the Korean War, General Douglas MacArthur was relieved by President Harry Truman in 1951 for publicly opposing presidential policy and advocating an expanded war against China.
Earlier still, in World War II, General Lloyd Fredendall was removed in 1943 due to poor performance and disciplinary failures in North Africa. During the U.S. Civil War, General George B. McClellan was relieved in 1862 by President Abraham Lincoln for failing to act decisively and for delaying offensive operations, contrary to Lincoln’s strategy for the Union armies.
Throughout U.S. history, these removals have occurred for three main reasons: political or policy disagreements, military failure or strategic missteps, and ethical or administrative concerns. While the reasons vary, a consistent thread is the reinforcement of civilian supremacy, ensuring that military leadership aligns with elected civilian authority and national objectives. The events of 2026, however, demonstrate how rapidly changing geopolitical and wartime conditions can create unprecedented scenarios in which the balance between professional military judgment and political alignment comes under intense scrutiny.
