The 2022 Force Model and the 2023 regional plans replaced force generation with pre-assignment, so the binding question became movement rather than numbers. The infrastructure that would carry those forces is civilian, partly incomplete, and on the Baltic corridor still being built to a new gauge.
Written for geopolitical-risk and economic-exposure work: it traces a mechanism, not a market view.
How to read the grades
- Confirmed Documented as having occurred, with sources.
- Plausible exposure A mechanism Vigil assesses as likely; not documented as having occurred.
- Unconfirmed scenario Named because it is worth watching. Not asserted.
A step can never be graded more firmly than the step it depends on: a consequence cannot be better established than its cause. That rule is enforced when this site is built, not applied by hand — a chain that broke it would fail the build rather than publish.

- Affected asset, route or regionConfirmed
The asset at issue is the transport system of NATO's eastern members — the rail, road and port infrastructure over which reinforcement would move. It is civilian, commercially operated, and in the Baltic states historically built to the Russian 1,520 mm gauge rather than the European standard, which is the problem Rail Baltica exists to solve.

Pre-assignment changes what the system is asked to do. NATO describes the Force Model as a larger pool of high-readiness forces that can be pre-assigned to specific plans, and the Vilnius plans as improving the coherence of collective defence planning with Allies' national planning of forces, posture and command and control. A force assigned to a plan is a force that must be able to arrive where the plan puts it, on the timescale the plan assumes.
Documented as having occurred, with sources.
- Exposed sector or commodityPlausible exposure
The exposure is infrastructure capacity and host-nation support: the gauge break at the Baltic frontier, the completion schedule of the new standard-gauge line, bridge and axle-load limits on the existing network, and the arrangements under which a host state receives, moves and sustains forces that are not its own. NATO's own list of reinforcement measures names a new policy for improving logistics support to move, reinforce, supply and sustain forces — which states that the requirement exists, not that it is met.

- Broader economic significancePlausible exposure
The consequence for how this theatre should be read is that force numbers are the wrong measure of it. Between 2022 and 2026 the Alliance changed what its forces are for and how they are held; it did not, and could not on the same timescale, change the railways, roads and ports that would carry them. Whether the two are in step is a question about construction schedules and civil infrastructure, and it is not answerable from any military source.

Sectors and commodities exposed
Named as plain labels rather than a controlled vocabulary, so this list cannot drift from the commodity names the module's economy section already uses.
What remains unknown
- No capacity figure, transit time, corridor or route is carried in this chain, and none should be added: the module refuses reinforcement-planning detail by design.
- Which forces are assigned to which plan is not published, so the size of the movement requirement cannot be stated.
- Host-nation support arrangements are bilateral and largely unpublished.
Readings the evidence also supports
- The infrastructure constraint may be smaller than it appears: allied movement in exercises has repeatedly been demonstrated, and a plan does not require the whole assigned force to arrive simultaneously. The public record establishes the requirement and the infrastructure programmes; it does not establish a shortfall, and this chain does not assert one.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
Rail Baltica completion milestones against published schedules
The joint venture's own documents are the source of record. A slipped milestone is a movement constraint, not a construction story.
Whether NATO publishes implementation milestones for its logistics policy
NATO states the policy exists. No milestone, target or measure has been published, so there is nothing yet to track it against.
