What Military Power Assessments Actually Measure
Official assessments separate overseas basing, command arrangements and how many wars a force is sized to fight. No single figure ranks overall military power.
WASHINGTON, Nov. 6, 2026 — Public arguments about “military power” often collapse several different measurements into one ranking. Official U.S. sources treat those measurements separately. One count is where forces are stationed. Another is how the chain of command is organized. A third is how many overlapping wars a force is sized to fight. None of those figures, on its own, answers whether a military would prevail in a particular campaign.
The Congressional Research Service’s July 2024 study of overseas basing is an example of the first kind of measure. It found that the Defense Department “manages or uses at least 128 overseas bases in at least 51 different countries,” and it used March 2024 Defense Manpower Data Center figures to describe personnel “permanently assigned” to those sites — about 81,000 in the Indo-Pacific, including 54,774 in Japan and 24,234 in South Korea, and about 67,200 in Europe, including 35,068 in Germany. CRS warned that those totals exclude most temporary and rotational deployments, which can change the picture quickly.
Command, posture and the one-war planning standard
A second measurement is organizational. CRS’s primer on combatant commands explains that operational control runs from the president to the secretary of defense to the combatant commanders, and that the Unified Command Plan assigns missions and geographic or functional responsibilities. Knowing that a theater has a four-star commander does not, by itself, describe the units assigned to that commander on a given day.
A third measurement is the force-planning standard — the number of conflicts the military is built to handle at once. In its August 2024 report on great-power competition, CRS wrote that this standard “can strongly impact the size of the U.S. defense budget.” It quoted Adm. Michael Gilday’s May 12, 2022, testimony that the force was “sized to fight one and to keep a second adversary in check,” not to handle “two all-out conflicts.” The 2022 National Defense Strategy, CRS said, similarly described a force sized to defend the homeland, maintain strategic deterrence, and deter and, if necessary, prevail in conflict, while using allies, nuclear deterrence and other tools to reduce the risk of a second major war.
Those three measurements can move in different directions. A country may host many permanently assigned U.S. troops and still be a poor location for a particular contingency. A combatant command may exist on paper while the units it would need are committed elsewhere. A one-war planning standard may be judged adequate for peacetime presence and inadequate if two peers act at once — a possibility CRS notes that some members of Congress and a 2024 congressional commission have asked the department to revisit.
Assessing military power, in this official literature, is less like reading a scoreboard and more like checking several instruments. Posture numbers describe where people and bases sit. Command charts describe who is authorized to issue orders. Force-planning language describes what the budget is supposed to buy. A serious comparison uses all three, dated to the reports that published them, and resists the temptation to treat any one figure as a final ranking. Assessment coverage continues on the military analysis hub and Military & Defense. Related explainers include combatant commands and overseas deployments.
