Title 10 › Subtitle Subtitle A— General Military Law › Part II— PERSONNEL › Chapter 32— OFFICER STRENGTH AND DISTRIBUTION IN GRADE › § 526
Sets a cap on how many top officers can be on active duty in each military service. The limits are: Army 219, Navy 150, Air Force 168, Marine Corps 64, and Space Force 24. The Secretary of Defense can call up to 232 officer jobs as “joint duty” so those jobs do not count against the service limits. Unless the Secretary decides a lower number is better, at least these joint jobs must be from each service: Army 75, Navy 53, Air Force 68, Marine Corps 17, Space Force 6. Some officers do not count against the caps. That includes reserve or Space Force officers on active duty for training or for less than 180 days. Reserve officers can be put on active duty for 180 to 365 days if authorized, but the number in each service cannot be more than 10 percent of that service’s authorized generals or flag officers under section 12004 (fractions are rounded down to the next whole number greater than zero). The Air Force Secretary may allow up to two Space Force generals to serve 180–365 days. Reserve or Space Force officers may be on active duty longer than 365 days and up to three years, but no more than five such officers per service who are not in joint jobs, unless the Secretary of Defense approves more. Short stopgap rules let officers count as active for up to 60 days when they are on leave before retirement, between assignments, or in certain Space Force transitions. A temporary joint job can be excluded for up to one year. An officer leaving a joint job is excluded for 60 days; that 60-day period can be extended by 120 days, but only three officers per service may have that extra extension at the same time. The Marine Corps’ Medical Officer is exempt. Up to 35 positions can be designated as the Secretary of Defense Adaptive Force Account and not count against the limits. If a service secretary wants to take an action that would raise a service’s active top-officer count above the “baseline,” they must notify the Armed Services Committees and wait 60 calendar days. The baseline is the lower of the statutory limit or the actual number counted on January 1, 2023. The same 60-day rule and baseline apply to actions that would raise the number of joint-duty officers. Each year by March 1, the Secretary of Defense must report the numbers as of January 1. The Secretary of Defense may also shift some one- and two-star slots between services, but each increase must be matched by a one-for-one reduction in another service (not the Coast Guard). The total number of such increases, combined with related increases under section 526(k)(1), cannot exceed 15 at one time. No such increase can take effect until 30 days after written notice of the change and the matching reductions is sent to the Armed Services Committees.
