From the Introduction: "Russia's full-scale invasion of neighboring Ukraine in February 2022 marked the start of Europe's deadliest armed conflict in decades. It also prompted intensive international efforts to respond to the war. Multiple Members of Congress have engaged with U.S. and international measures, including by considering sanctions against Russia, providing assistance to Ukraine, and bolstering support to neighboring NATO countries. The immediate and long-term implications of the war are likely to be far-reaching, affecting numerous policy dimensions of concern to Congress. This report addresses military and intelligence aspects of Russia's war in Ukraine, which are of interest to many in Congress as Congress considers various legislative measures and conducts oversight of U.S. policy. It provides an overview of the conflict, including the run-up to the invasion, the performance and conduct of the Russian and Ukrainian militaries, possible Russian intentions, and recent developments."
