Armenia → Russia in the Caucasus

The parties

• Armenia hosts a military presence belonging to Russia in the Caucasus
• Russia in the Caucasus maintains a presence hosted by Armenia

A directional arrangement: the two parties do not hold the same position in it. Authored once and read from both ends.

What the arrangement covers

Categories the arrangement is documented to include. Not a measure: a relationship covering more of them is described in more detail, not held more firmly.

Summary

Russia's 102nd Military Base at Gyumri, near the closed Turkish frontier, is held under a lease agreement extended to 2044. It has not been affected by the realignment around it. Armenia froze its participation in the Russian-led collective security organisation in February 2024, and Russian border guards have left every Armenian checkpoint — Zvartnots in August 2024, the Iranian crossing in January 2025, Margara in March 2025 and Akhurik from the start of 2026. The base remains, and Armenia has not proposed changing the lease. The two halves are the point: Armenia has ended the arrangements it could end by agreement and left untouched the one governed by a lease with eighteen years to run. Vigil publishes nothing about the base beyond its existence, its publicly documented location and its political significance.

Why it matters

Describing Russia as having left Armenia, or as still policing its borders, are both wrong, and this record is what makes the difference legible. It is also the standing reason Armenia's realignment is incremental rather than a rupture: the instrument it has not touched is the one it could not end unilaterally.

Organisations

Structures through which this relationship operates. Not parties to it — the parties are the two actors above.

What remains unknown

• This module records the lease term and the base's presence, and not the date the arrangement began. `validFrom` is given as 1992, the post-Soviet baseline, and is context rather than a claim these sources establish. The load-bearing dates here are the lease running to 2044 and the 2024–2026 border-guard withdrawal.
• Vigil publishes no strength, disposition, capability or activity for the base, and the absence is structural rather than a gap this record expects to fill.
• Whether the border-guard withdrawal was Armenian-initiated in every case, or agreed on Russian terms in some, is not established by available reporting.

Readings the evidence also supports

• The retention of the base can be read as a deliberate hedge — an option Armenia preserves against a security environment it cannot otherwise cover — or simply as the arrangement it has no unilateral means to end. Its behaviour, which is to leave the lease unmentioned while ending everything around it, is consistent with both.

Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
