Retired General Mark Milley spent over four decades in uniform, culminating as the 20th Chairman of the Joint Chiefs of Staff. Appointed by Donald Trump and later serving under Joe Biden, Milley became one of the most visible and politically polarizing military leaders in modern American history. He navigated high-stakes geopolitical crises, major institutional reforms, and intense political friction that dragged the armed forces directly into the cultural and partisan crosshairs.
Understanding Milley's legacy requires looking past partisan headlines to examine his actual command decisions, institutional policies, and the specific controversies that defined his tenure.
Early Life, Education, and Rise Through the Ranks
Born in Winchester, Massachusetts, in 1958, Milley attended Princeton University, where he played ice hockey and earned his commission through the Army Reserve Officers' Training Corps (ROTC) program in 1980. Unlike officers who spend their careers behind desks, Milley built a reputation as an infantry and Special Forces officer, deploying across multiple global conflicts.
His early service included operational deployments during Operation Just Cause in Panama and Operation Uphold Democracy in Haiti, alongside peacekeeping missions in Bosnia and Herzegovina. As he climbed the command ladder, he led the 2nd Brigade Combat Team of the 10th Mountain Division, commanded the entire 10th Mountain Division, and later served as the commanding general of III Corps and U.S. Army Forces Command.
Chief of Staff of the Army
In 2015, Milley took over as the 39th Chief of Staff of the Army. During his tenure, he pushed aggressively for force modernization. Recognizing that decades of counterinsurgency warfare in Iraq and Afghanistan had left the service behind in conventional readiness against near-peer adversaries like Russia and China, he championed structural reforms.
His most notable institutional creation was the establishment of Army Futures Command in Austin, Texas. This command centralized the modernization process, focusing research and development on long-range precision fires, next-generation combat vehicles, and integrated air defense. He also oversaw the rollout of the Army Green Service Uniform and updated physical fitness standards to match modern combat requirements.
Chairman of the Joint Chiefs of Staff
In October 2019, Milley stepped into the role of Chairman of the Joint Chiefs of Staff, serving as the principal military advisor to the president. This position thrust him straight into the center of turbulent domestic politics and historic foreign policy crises.
The St. John's Church Photo-Op
One of the earliest and most damaging controversies erupted in June 2020. Following nationwide civil unrest after the murder of George Floyd, federal law enforcement and military police cleared protesters from Lafayette Square near the White House. Milley, wearing his combat uniform, walked alongside President Donald Trump to St. John's Church, where the president held up a Bible.
The backlash was swift. Critics accused Milley of politicizing the military by appearing alongside the commander-in-chief in a domestic political context. Weeks later, in an address at the National Defense University, Milley publicly apologized, stating that his presence "created a perception of the military involved in domestic politics" and that he "should not have been there."
Managing the Transition and Calls to China
As the 2020 presidential election gave way to political turbulence, Milley took unprecedented steps behind the scenes. Concerned about the mental state of the outgoing president and the risk of sudden military escalation or unauthorized orders, Milley held two secret phone calls with General Li Zuocheng of the People's Liberation Army of China.
Milley assured his Chinese counterpart that the United States was stable and that he would provide advance warning if any military strike were planned. While supporters defended these actions as a necessary guardrail against constitutional crisis, severe critics labeled the calls an overreach of his authority, arguing he stepped outside the chain of command.
The Afghanistan Withdrawal
In August 2021, Milley faced immense scrutiny over the chaotic U.S. military withdrawal from Afghanistan. The rapid collapse of the Afghan government and the deadly bombing at Hamid Karzai International Airport during the evacuation raised hard questions about intelligence failures and military planning.
During congressional testimony, Milley defended the execution of the retrograde operation under extremely difficult constraints, though he acknowledged that the strategic outcome was a "strategic failure" that had taken twenty years to build.
Key Controversies and Criticisms
Milley's tenure was marked by frequent clashes with civilian leadership and public debates over the direction of the armed forces.
- Critical Race Theory and Diversity Initiatives: Conservative lawmakers heavily criticized Milley after he defended teaching critical race theory concepts at military academies. He argued that military leaders needed to understand the sociological factors affecting the force, stating that it was important to be "open-minded" and understand systemic issues. Critics countered that these initiatives degraded unit cohesion and introduced partisan politics into the ranks.
- Openness to Partisan Friction: Throughout his career, Milley maintained that the military must remain strictly apolitical while simultaneously defending institutional policies against political attacks. This tightrope walk left him vulnerable to criticism from both sides of the political aisle.
