In eastern Ukraine, many of the defensive lines built by pro-Russian and Ukrainian forces during fighting between 2014 and 2022 are now inside Russian-occupied territory.

This map update shows where these older fortifications overlap with newer defenses. (1/8)

A few important notes on this map of fortifications in eastern Ukraine from 2014 to 2022:

First, this data only reflects trenches, barriers, and revetments built before February 2022 that are now within territory occupied by Russian forces. (2/8)

Second, Russian forces have not maintained or expanded most of these positions which dramatically reduces their usefulness when compared to newer defenses. (3/8)

Third, this data is not exhaustive and there may be older fortifications not shown on the map. (4/8)

Nature has overtaken many of the older defensive lines built in eastern Ukraine between 2014 and 2022.

Others are in better condition but still poorly positioned for the current front line. (5/8)

In several instances, new fortifications constructed by Russian forces intersect older defensive lines. (6/8)

In other areas, older fortifications have been expanded and upgraded since Russia’s full-scale invasion of Ukraine in 2022. (7/8)

A big thanks to @DefMon3, who provided a lot of the data for this map update.
