Defense Secretary Pete Hegseth announced a new Joint Warfighter Evaluation that will force colonels and Navy captains to prove they can fight and win under simulated combat pressure before earning a star.

Hegseth rolled out the program Tuesday in a video posted to social media, declaring that the Defense Department will begin screening senior officers on operational decision-making rather than career credentials alone. The evaluation targets O-6 ranked officers, colonels in the Army, Air Force, Space Force, and Marine Corps, and captains in the Navy, who are eligible for promotion to one-star general or admiral.

The move marks the most concrete step yet in Hegseth's campaign to reshape how the Pentagon selects its top leaders. For decades, promotion boards have weighed officers primarily on accumulated performance evaluations written by their superiors over the course of a career. The new assessment adds a separate, standalone test of battlefield competence, wargames, simulations, and written analyses designed to measure whether a candidate can plan and execute under pressure, not just manage upward.

Six branches, six tests, each built around combat scenarios

Internal documents obtained by The Hill show that each military branch will run its own version of the evaluation, tailored to its operational domain. The Army will use a written assessment followed by a digital wargame. The Air Force and Space Force will require a two-hour online analysis test and then a one-hour interactive simulation.

The Navy's version sends officers to the Naval War College for a three-hour written assessment and a two-to-three-hour wargame. The Marine Corps demands the most time: an eight-hour remote evaluation on an AI-enabled platform that combines written assessments with situational judgment tests.

The Joint Staff, meanwhile, will evaluate 50 to 60 students at the Joint Forces Staff College in Norfolk, Virginia, using what an internal memo from Under Secretary of Defense for Personnel and Readiness Anthony Tata describes as a "hybrid" model, an independent written analysis followed by an "in-person, AI enabled execution phase." That memo, dated August 12 and reviewed by The Hill, also directs each service to provide weekly updates on its pilot program development.

Stuart Scheller, the senior Pentagon adviser leading the effort, was tasked by Hegseth roughly a year ago to build the evaluation framework. Scheller, who serves as deputy chief of staff to Tata, told Fox News that the current system rewards career navigation over combat skill.

"People figure out they don't have to be the best at their job, they have to be the best at making sure their boss thinks they're the best. And those are actually two very different things."

Scheller added that there is no existing "stand-alone function that can truly assess the best military commanders on the battlefield." The new evaluation is designed to fill that gap.

First evaluation cycle targets early 2027

Fox News reported that the first evaluation cycle will run from February through June 2027, with O-7 promotion boards following between July and September of that year. That timeline means the Pentagon is moving fast, building, piloting, and deploying six distinct assessment programs inside a single fiscal year.

Hegseth framed the initiative as a return to a proven model. In his video announcement, he pointed to the Louisiana Maneuvers, a massive pre-World War II exercise in which roughly 400,000 troops participated in wargames designed to test training, logistics, and leadership. Those maneuvers identified and elevated commanders who went on to shape the war, among them Dwight Eisenhower, who planned the Allied assault on Normandy; Omar Bradley, who became the first chairman of the Joint Chiefs of Staff and oversaw military policy during the Korean War; and Admiral Chester Nimitz, who commanded Allied forces across the Pacific theater.

Hegseth said the Joint Warfighter Evaluation "brings that standard to the modern multi-domain fight." He has consistently argued that the Pentagon's promotion pipeline has drifted away from selecting leaders who can perform under fire. In remarks to senior military leaders at Quantico, Virginia, last year, he put the point bluntly.

"Real toxic leadership is endangering subordinates with low standards. Real toxic leadership is promoting people based on immutable characteristics or quotas instead of based on merit."

The evaluation, Hegseth said in his announcement, is meant to function as "an objective equalizer." He added: "The scenario only cares about operational decisions under pressure."

The Washington Examiner reported that the program will apply to select general promotions beginning this year, with eligible colonels and Navy captains screened on their ability to "fight, adapt, and win" in what Hegseth called "a chaotic battle space."

Blocked promotions signal Hegseth means it

The new assessment does not exist in a vacuum. Hegseth has already blocked numerous Army, Navy, and Air Force promotions to one-star general or admiral, signaling that he views the current pipeline as broken. The Hill reported that a large number of the blocked promotions involved Black and female service members, though the specific cases and the criteria behind each decision were not detailed in the reporting.

Hegseth has argued, without the article citing specific evidence, that some promotions were driven by race and gender quotas rather than merit. His critics see the blocked promotions as politically motivated. But the new evaluation framework shifts the debate onto different ground: if every candidate for a star must now pass a standardized battlefield test, the results become harder to dismiss as subjective or ideological.

That is, of course, the point. A system that grades officers on simulated combat performance rather than supervisor evaluations removes a layer of institutional discretion, the same layer Hegseth has argued allowed political considerations to creep into the promotion process.

Hegseth has also moved to halt promotions of officers linked to removed generals, part of a broader effort to reshape the Pentagon's leadership culture from the top down.

Warfighter ethos meets AI-powered simulation

The technical design of the evaluations reflects a deliberate blend of old-school military thinking and modern technology. The Marine Corps' eight-hour AI-enabled platform and the Joint Staff's "AI enabled execution phase" suggest the Pentagon is building assessment tools that can simulate adversary behavior, develop unpredictable scenarios, and score decision-making in ways that a paper review board cannot.

Hegseth noted that commanders should be chosen by "proven competence, not paper credential." The distinction matters. Under the existing system, an officer's path to a star depends heavily on how well superiors describe that officer's performance over a 25- to 30-year career. The new evaluation adds a direct, observable test, closer to a tryout than a résumé review.

Whether the Pentagon can build, calibrate, and deploy six branch-specific evaluations on the announced timeline remains an open question. The Tata memo's requirement for weekly progress updates suggests the department is aware of the execution risk. And the scope is significant: each branch must design scenarios that credibly test multi-domain operational thinking, not just tactical competence.

Hegseth's broader restructuring of Pentagon leadership has drawn scrutiny from both parties. Some Republican critics have joined Democrats in questioning the pace and scope of his changes. But the Joint Warfighter Evaluation is harder to attack on principle than personnel decisions made behind closed doors. A standardized combat test is, by design, the kind of meritocratic tool that critics of the old system, left and right, have long said the military needs.

Hegseth has also taken steps to tighten control over Pentagon operations more broadly, including forming a joint task force with the Department of Justice to address unauthorized disclosures of internal information.

The standard the Pentagon forgot

The Louisiana Maneuvers comparison is more than historical decoration. Before the United States entered World War II, the military staged the largest peacetime exercise in its history, not to train troops, but to find out which commanders could actually lead under pressure. Officers who failed were removed. Officers who performed were fast-tracked. The result was a generation of wartime leaders selected on demonstrated ability, not seniority or connections.

Hegseth is betting that a modern version of that test, shorter, digitized, AI-enhanced, can do something similar. The Pentagon's promotion system has operated for decades on the assumption that career-long evaluations from superiors provide an adequate picture of an officer's readiness for command. Hegseth and Scheller are arguing that assumption is wrong, and that the only way to know whether a colonel can command in combat is to put that colonel in a simulated fight and watch what happens.

The first candidates will face that test early next year. How they perform, and how the Pentagon uses the results, will determine whether the Joint Warfighter Evaluation becomes a lasting reform or a one-cycle experiment.

For decades, the Pentagon promoted officers based on what their bosses wrote about them. Hegseth is adding a simpler question: can you fight? If the answer matters as much as the Defense Secretary says it does, the military's leadership pipeline is about to look very different.
