4th Guards Military Base
Identification
This record matches Russia’s 4th Guards Military Base in South Ossetia/Tskhinvali region, subordinate to the 58th Combined Arms Army. Multiple sources place the base’s two main components in Tskhinvali and Dzau/Java, which is consistent with the supplied placemark pattern.

Footprint
The identifiable footprint is split between a Tskhinvali-area garrison and the Java/Dzau camp, with the Dzartsemi training range north of Tskhinvali tied to the base. Transparency International Georgia maps the Java base at 42°23'11.50"N 43°53'17.37"E and the Dzartsemi range at 42°18'04.94"N 43°57'34.28"E; those locations align closely with the supplied placemarks if the coordinates are being recorded in longitude/latitude order.

Force posture
CNA assesses the 4th Military Base as a brigade-strength formation whose main elements are in Tskhinvali, with one tank battalion, three motor-rifle battalions, an MLRS artillery battalion, and a 9K37 Buk-M1 air-defense battalion. That supports the record’s general armor/artillery/air-defense characterization, but I did not find authoritative open sources that independently confirm the exact location of the specific placemark labeled as the anti-aircraft missile division.

Basing and command
Russia and South Ossetia signed a basing agreement on 7 April 2010 giving the unified Russian base a 49-year term with automatic extension provisions, and a further 31 March 2017 agreement allowed some South Ossetian personnel to enter Russian service at the base. The metadata naming Colonel Roman Vyazovsky appears outdated: South Ossetian state media still referenced him in January 2022, but on 1 February 2026 the same outlet identified Rajab Aliyev as acting commander at the base’s 17th-anniversary event.

Operational relevance
The base is Russia’s standing ground combat position inside South Ossetia for the 58th CAA and sits on the Tskhinvali/Java axis that underpins access from North Ossetia into the region. Public reporting in March 2022 said elements of the 4th base were redeployed from South Ossetia toward the Ukraine theater; South Ossetian leader Anatoly Bibilov publicly acknowledged that 4th-base units had been sent, but reported force levels varied and should be treated as unconfirmed in exact number.
