The Sentinel Review Ukraine theater tracks the eastern front of the Russia–Ukraine war, with primary focus on Donetsk and Luhansk oblasts where the bulk of contact, artillery, and strike activity is concentrated. We pull from Ukrainian and Russian milblog channels, regional press, OSINT geolocators, and wire services, then cross-reference each event across independent sources before publishing.

Coverage extends across the broader bounding box of mainland Ukraine and adjacent Russian border regions where cross-border strikes and incursions occur. We do not synthesize political analysis — events are presented as discrete, geolocated facts with confidence levels that reflect the corroboration we have.
