The Pentagon this week rolled out a new “battlefield” assessment that colonels and Navy captains must pass before being promoted to one-star general or admiral, part of Defense Secretary Pete Hegseth's push to reshape how the military picks its top leaders, per Fox News.

Why it matters: The current promotion system leans heavily on career evaluations and supervisor ratings — which Hegseth argues rewards officers skilled at managing their image up the chain rather than actually leading troops in combat.

Driving the news:

  • The new Joint Warfighter Evaluation (JWE) puts eligible O-6s — colonels and Navy captains — through simulated combat scenarios testing decision-making, adaptability and problem-solving before they can screen for their first star.

  • Each service branch built its own version: the Army's colonels face written assessments plus digital wargames; the Air Force's do two-hour online tests plus hour-long simulations; the Navy's captains attend the Naval War College for three-hour written exams and two-to-three-hour wargames; the Marine Corps's colonels undergo eight-hour remote evaluations using AI platforms; and the Space Force uses the Air Force's format.

  • Stu Scheller, the senior Pentagon adviser leading the effort, said the old system let officers get by without being the best at their job: “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,” per Fox News.

By the numbers:

  • ~900 — Army colonels eligible for the new assessment.

  • ~1,330 — Air Force colonels eligible.

  • ~308 — Navy captains eligible.

  • ~175 — Marine Corps colonels eligible.

  • ~125 — Space Force officers eligible.

What they're saying: Hegseth said: “Starting this year, eligible O-6s — that's colonels and Navy captains — screening for one star will undergo this assessment to stratify their ability to fight, adapt, and win. While the backbone of our military is our NCOs and our petty officers, victory depends on the commanders who lead them. America needs warfighters who can master a chaotic battle space.” Washington Examiner reported Hegseth cast the new test as an “equalizer” in how the Pentagon selects its next generation of generals.

What's next: The first cohort sits for testing between February and June 2027, with the promotion boards that actually decide who pins on a star convening that July through September for the fiscal year 2027 cycle.

The bottom line: Hegseth is betting that a standardized, combat-style test can do what career evaluations haven't — surface the officers most likely to perform under real battlefield pressure — but the real verdict on whether it changes who actually gets promoted won't be clear until next year's boards convene.
