Title 10 › Subtitle A — General Military Law › PART II — PERSONNEL › CHAPTER 32 — OFFICER STRENGTH AND DISTRIBUTION IN GRADE › § 526
Limits how many top officers each service can have on active duty. The cap is Army 219, Navy 150, Air Force 168, Marine Corps 64, and Space Force 24. The Secretary of Defense may set up to 232 joint-duty positions that do not count against those caps. Unless the Secretary says otherwise, at least these numbers of those joint-duty slots should go to each service: Army 75, Navy 53, Air Force 68, Marine Corps 17, Space Force 6. Some officers do not count toward the caps. That includes reserve or Space Force officers on short active duty for training or orders under 180 days. The military secretaries may approve some reserve officers to serve 180–365 days. Each reserve component may use up to 10% (round down) of that service’s authorized general/flag officer total for those 180–365 day tours. The Air Force may allow up to two Space Force generals that way. Officers who serve longer than 365 days but no more than three years also can be excluded, though normally no more than five such officers per service are allowed unless the Secretary of Defense approves. Officers on leave before retirement or between senior jobs are excluded for up to 60 days. Temporary joint-duty assignments can be excluded for up to one year. Officers leaving joint duty are excluded for 60 days; the Secretary of Defense can let a service extend that by 120 days but only three officers per service can have that extension at the same time. The Marine Corps’ Medical Officer and up to 35 officers assigned to the Secretary of Defense Adaptive Force Account are also excluded. If a military secretary wants to increase a service’s counted officers above the baseline, or if leaders want to add counted joint-duty slots above the joint baseline, they must tell the congressional Armed Services Committees and wait 60 days. The baseline is the lower of the legal cap or the number that counted on January 1, 2023. The Secretary of Defense must send a report each year by March 1 showing the January 1 counts. The Secretary of Defense may move some two-star and equivalent slots between services, but each increase must be balanced by a cut elsewhere, total transfers may not exceed 15 at once, and the Secretary must give 30 days’ written notice to Congress listing the changes.
