## What it is

"Forward posture" describes a military strategy in which forces are stationed or rotated close to a potential adversary rather than held in reserve at home-country bases. Two models compete: permanent basing, where troops serve in a host country on multi-year tours; and rotational presence, where units cycle through on assignments of six to nine months before returning home. NATO's current hybrid approach relies on rotational deployments backed by pre-positioned equipment, a posture shaped by domestic budget pressures, host-nation politics, and the ongoing debate over whether rotation can substitute for permanent commitment as a deterrence signal.

The principal actors are the United States European Command (EUCOM), headquartered in Stuttgart, Germany; NATO Supreme Allied Commander Europe (SACEUR); and the host-nation governments whose basing agreements make the posture legally possible.

## History

During the Cold War, the United States kept over 300,000 troops permanently in West Germany and across Western Europe. After the Soviet Union's dissolution those numbers fell sharply: by 2013 the US had fewer than 70,000 personnel in Europe and had withdrawn its last Main Battle Tanks from the continent.

Russia's annexation of Crimea in 2014 prompted the launch of Operation Atlantic Resolve, which began cycling US armored, aviation, and logistics units through Poland and the Baltic states on nine-month rotations. NATO's 2016 Warsaw Summit formalised the Enhanced Forward Presence (EFP), creating four multinational battlegroups in Estonia, Latvia, Lithuania, and Poland as a tripwire layer rather than a standalone defence.

Russia's full-scale invasion of Ukraine in February 2022 triggered a surge: US troop levels in Europe briefly exceeded 100,000, NATO expanded EFP to eight battlegroups across its eastern flank, and V Corps was reactivated and based in Poznan, Poland.

## Current state

Approximately 80,000 US military personnel remain in Europe as of early 2026, but the posture is under deliberate pressure from Washington. In May 2026 the Pentagon withdrew 5,000 troops from Germany and canceled an armored brigade rotation to Poland. US Defence Secretary Pete Hegseth announced on June 18, 2026, a formal review of US Europe force posture, conditioning future deployments on whether allies had provided base access and overflight rights during the US war with Iran. He framed the review publicly as "a review that some countries will fail and others will pass with flying colors."

The structural shift is visible in the command hierarchy: the four-star USAREUR-AF billet held by General Christopher Donahue was downgraded to three stars, as documented in [the abrupt end of Donahue's tour](/ja/n/donahue-us-army-europe-hegseth-jun25). Poland may retain or gain a separate bilateral US troop commitment of 5,000, potentially shielding it from the broader review.

## Relationships

Forward posture is the operational expression of NATO's deterrence commitment; changes to it signal alliance reliability to both Russia and European member states. The US pressure is accelerating European efforts to build independent capacity, extending the concept geographically: Germany's readiness to deploy Bundeswehr minesweepers to the Strait of Hormuz, outlined in [メルツ首相、ドイツ海軍掃海艦がホルムズ海峡を警備できると示唆](/ja/n/merz-iran-hormuz-bundeswehr-2026), reflects European allies probing forward roles beyond the NATO area, partly to demonstrate strategic credibility with Washington.

## What to watch

- The outcome of Hegseth's posture review and which European allies it exempts or penalises.
- Whether the US armored brigade rotation to Poland is reinstated or replaced by a bilateral basing deal.
- European NATO members' progress toward the 5 percent of GDP defence spending target demanded by Washington.
- Germany's Bundestag vote on a Bundeswehr Hormuz mandate.
- Russia's operational assessment of NATO's effective eastern-flank coverage as the US institutional profile in Europe declines.
