Army Surgeon General: Role, Appointment, and Priorities

The Army Surgeon General is the senior medical officer of the United States Army and the principal health advisor to the Secretary of the Army and the Army Chief of Staff. The position is codified at 10 U.S. Code § 7036, and the person holding it simultaneously commands the U.S. Army Medical Command (MEDCOM). The office was created by Congress in 1818. The current officeholder, Lieutenant General Mary K. Izaguirre, became the 46th Army Surgeon General in January 2024.¹²

What the Job Involves

Two roles sit on the same set of shoulders. As Surgeon General, the officer advises Army leadership on health policy and serves as chief medical advisor to the Director of the Defense Health Agency on Army readiness matters. As Commanding General of MEDCOM, the same officer is responsible for organizing, training, and equipping the Army’s medical forces so they can deploy and sustain combat power. In practical terms, the office decides how Army medicine is staffed, trained, and postured, and speaks for the Army on medical questions to the rest of the Department of Defense.¹³

The role is often confused with the U.S. Surgeon General, who leads the U.S. Public Health Service Commissioned Corps and speaks publicly on national health matters. They are separate jobs. The Army Surgeon General’s mandate is military and Army-specific: Army medical personnel, Army readiness, Army medical doctrine.¹

How the Officer Is Appointed

The President appoints the Army Surgeon General, with the advice and consent of the Senate, from officers serving in any corps of the Army Medical Department. The term is normally four years, though the President may terminate or extend it at any time. Because the position carries the three-star grade of lieutenant general, the nominee must be confirmed twice under the Constitution’s Appointments Clause: once for the office and once for the associated rank.¹⁴

Candidates are typically vetted first through the Department of Defense’s General and Flag Officer Management Office. A slate goes to the President, who nominates a candidate to the Senate; the nomination is referred to the Senate Armed Services Committee, and if it advances, the full Senate votes. Most military nominations pass by unanimous consent, but any senator can impose a hold and force floor time.⁵

What the Office Commands

MEDCOM is headquartered at Joint Base San Antonio–Fort Sam Houston, Texas. Its stated mission is to “provide ready and sustained health services support and force health protection in support of the Total Force to enable readiness and to conserve the fighting strength while caring for our People and their Families.”³

The command is organized around four geographically aligned Medical Readiness Commands (MRCs), which were re-designated from the former Regional Health Commands in late 2022 to sharpen their focus on operational readiness under a National Defense Authorization Act mandate:

MRC, East, re-designated September 8, 2022 (formerly Regional Health Command–Atlantic).
MRC, West, re-designated September 13, 2022 (formerly Regional Health Command–Central).
MRC, Europe, re-designated September 30, 2022.
MRC, Pacific, re-designated October 18, 2022.⁶

Other subordinate elements include the U.S. Army Health Contracting Activity and the Army Recovery Care Program. The Army Medical Center of Excellence (MEDCoE), also at Fort Sam Houston, is not part of MEDCOM. It falls under the Army’s Training and Doctrine Command and serves as the proponent for medical doctrine and education, home to the 32d Medical Brigade, the Army’s largest training brigade. MEDCoE works in close coordination with the Surgeon General’s office.⁷

How the Defense Health Agency Reshaped the Role

The 2017 National Defense Authorization Act required the Defense Health Agency (DHA) to assume authority over all military hospitals and clinics, transferring them out of the individual services. That change fundamentally reshaped what the Army Surgeon General does day-to-day.⁸

The transition was contentious. In August 2020, secretaries and top officials of each military branch signed a joint memo calling for an immediate halt, arguing that the DHA model “introduces barriers, creates unnecessary complexity and increases inefficiencies and cost.” Then–Army Secretary Ryan McCarthy said the merger was moving “too fast” and risked “the healthcare of our soldiers and their families.” The Department of Defense pressed forward, and COVID-19 delayed rather than derailed the process.⁹

Under the restructuring plan submitted to Congress in February 2020, the Department evaluated 77 facilities: 50 were identified for restructuring (five for closure, 37 for conversion to active-duty care clinics, and the rest into other categories), 21 were left unchanged, and six were deferred for further review.¹⁰ Today, DHA manages the treatment facilities and organizes them into regional “markets,” while the Army Surgeon General retains authority to organize, train, and equip the Army’s medical forces for deployment. Some analysts describe the resulting dual-reporting arrangement as a persistent source of friction, particularly when DHA productivity benchmarks bump up against combat-readiness training requirements.¹¹

Where the Office Came From

Congress formally established the Office of the Surgeon General within the War Department on April 14, 1818. Before that date, Army medical care was ad hoc. Individual surgeons and mates served at posts or with regiments under local commanders, with no central medical authority. The 1818 statute created a permanent department and enabled systematic record-keeping.¹²¹³

Two officeholders in particular shaped what the position became. William A. Hammond, appointed the 11th Surgeon General in 1862, overhauled Union hospitals during the Civil War by emphasizing sanitation and ventilation, set minimum qualifications for surgeons, and created what is now the National Museum of Health and Medicine. He also launched the multi-volume Medical and Surgical History of the War of the Rebellion. His tenure ended when he was court-martialed in 1864 after a dispute with Secretary of War Edwin Stanton over medical supply purchases; Congress later restored him to the retired list with the rank of brigadier general.¹⁴¹⁵

Three decades later, George Miller Sternberg served as Surgeon General from 1893 to 1902. President Grover Cleveland picked him over ten more senior officers based on his scientific reputation. Sternberg founded the Army Medical School in June 1893 for postgraduate training in bacteriology, hygiene, and military medicine, and he mentored Walter Reed, whose team later demonstrated that yellow fever was transmitted by mosquitoes.¹⁶

Current Officeholder

Lt. Gen. Mary K. Izaguirre took command on January 25, 2024, in a ceremony hosted by Army Chief of Staff Gen. Randy George at Joint Base San Antonio–Fort Sam Houston. She is a board-certified family medicine physician with a Doctor of Osteopathic Medicine degree from the Philadelphia College of Osteopathic Medicine and a Master of Public Health from the University of Washington, along with advanced military degrees from the Command and General Staff College and the Eisenhower School for National Security.²¹⁷

Her career has covered command at every echelon of Army medicine. She ran a health clinic at Schofield Barracks in Hawaii, served as division surgeon for the 4th Infantry Division during operations in Iraq, and commanded both Tripler Army Medical Center and the Medical Readiness Command, East. Her decorations include the Army Distinguished Service Medal, two awards of the Legion of Merit, and the Bronze Star Medal.¹⁷

She succeeded Lt. Gen. R. Scott Dingle, the 45th Surgeon General, who served from 2019 to 2024 and retired after 34 years. Dingle was the first African American male to hold the position. His tenure was defined by the Army’s COVID-19 response: more than 3,200 soldiers and medics from MEDCOM deployed in support of the pandemic effort, and Dingle served on the White House’s Operation Warp Speed task force. He also oversaw the re-designation of the Regional Health Commands into Medical Readiness Commands.¹⁸¹⁹

Current Priorities

The Army Medicine Strategic Plan, published under Izaguirre’s leadership, describes an “Army Medicine of 2028” built around five lines of effort: recruiting and strengthening the medical profession; transforming Army medicine for multi-domain operations; sustaining health and preserving combat power; delivering a combat-ready medical force; and strengthening alliances and partnerships.²⁰

The central shift is away from the counterinsurgency-era assumption of reliable helicopter evacuation within an hour and toward preparation for large-scale combat against a peer adversary, where casualty rates are expected to be higher, evacuation routes may be contested, and supply lines can be cut. Near-term fielding includes prolonged care augmentation detachments, portable ultrasound, blood freezers, improved field ventilators, and freeze-dried plasma. Autonomous evacuation systems and AI-assisted diagnostics are envisioned further out.²¹

Workforce

Physician recruitment and retention are among the office’s most pressing problems. A 2024 RAND study conducted with the Army Office of the Surgeon General found that physician separations are outpacing new accessions, leaving unfilled positions at military treatment facilities and operational units. Researchers pointed to expanded military-civilian partnerships, wider options for partial civilian employment, and larger Army-sponsored graduate medical education programs, while cautioning that the fastest lever is monetary retention incentives.²²

The pay gap is significant. Military physicians in two-thirds of specialties cannot reach even the 20th percentile of civilian pay, and for procedural specialists the gap can exceed $400,000 a year. A June 2025 Inspector General report found that emergency medical officers in critical wartime specialties had been assigned to positions without direct patient care, causing their skills to fall below readiness standards. Nursing shortages have forced temporary service closures at Walter Reed National Military Medical Center, and behavioral health vacancies remain a persistent concern.²³²⁴

Holistic Health and Fitness

The Holistic Health and Fitness (H2F) program, piloted in 2018 and rolled out service-wide in 2020, is the Army’s primary framework for soldier performance. Each H2F performance team has 22 people: strength and conditioning coaches, a dietitian, a physical therapist, an occupational therapist, athletic trainers, and a cognitive performance specialist. As of 2026, sixty-six brigades have an active H2F team; full coverage of the active Army, portions of the National Guard, and two Army Reserve commands is planned by 2029. Early outcome data from the Center for Initial Military Training Research and Analysis showed units with H2F teams between 2019 and 2023 recording a 61 percent drop in musculoskeletal injury referrals, a 44 percent drop in behavioral health profiles, a 79 percent drop in substance abuse cases, and a 22 percent drop in fitness test failures.²⁵

MHS GENESIS

MHS GENESIS, the Military Health System’s electronic health record, completed worldwide deployment in March 2024 after a rollout that began in 2017. The system serves more than 207,000 end users across 138 military hospitals and clinics and over 3,600 Department of Defense locations, and it shares data with the Department of Veterans Affairs so that a service member’s record follows them from accession to veteran status. Watchdog reports have flagged clinician dissatisfaction with the system, which the Surgeon General’s office has treated as part of the broader administrative-burden problem driving retention challenges.²⁶²⁷

Behavioral Health and Suicide Prevention

Suicide prevention policy is managed through the Army’s Resilience Directorate rather than directly by MEDCOM, but the Surgeon General’s office shapes the clinical infrastructure that supports it. Army Regulation 600-92, effective September 2023, is the service’s first standalone suicide prevention policy and formalizes a public health approach aligned with CDC-recommended strategies. Supporting tools include the Commanders Risk Reduction Toolkit, which displays up to 40 risk factors in a single dashboard, and the Lethal Means Safety Toolkit, unveiled in 2023 to promote safe storage of weapons and medications. Annual Ask, Care, Escort–Suicide Intervention training is mandatory for all soldiers.²⁸
