Kursk Incursion Control of Terrain Shapefile Definitions:     

Ukrainian Advances in Russia are areas in Russia where ISW assesses Ukrainian forces have operated in or launched attacks against but do not control. We also use the concepts “forwards line of own troops (FLOT),” “line of contact,” and “forward edge of the battle area,” which all identify in slightly different ways the line separating friendly from enemy forces. The FLOT “is a line which indicates the most forward positions of friendly forces in any kind of military operation at a specific time... It does not include small, long-range reconnaissance assets and similar stay-behind forces.” (FM3-90-1). We largely use the Assessed Ukrainian Advances in Russia layer to depict areas within the Ukrainian FLOT but areas over which Ukrainian forces have not yet established control.  

The Russian Claims in Russia layer is an equivalent for the “Claimed Russian Control over Ukrainian Territory” layer, except for Russian territory as opposed to Ukrainian territory. The layer refers to territory that the Russians have claimed to be present in but that we cannot verify or have evidence disproving the Russian claim.
