Armiansk is a town in northern Crimea. It has been under Russian control since 2014 when Russia seized and annexed the Crimean peninsula.

Ukraine, preparing for a likely spring counteroffensive, would like to retake Crimea, which could be a "red line" for Russian President Vladimir Putin.

On April 3, 2023, The Washington Post reported that "a web of trenches shows Russia fears losing Crimea." ISW reported specific defensive preparations near Armiansk.
