MOSCOW >> The Russian military on Wednesday began a third round of drills with tactical nuclear weapons, part of the Kremlin’s messaging intended to force the West to limit its support for Ukraine.

The Russian Defense Ministry said the drills will feature units of the central and southern military districts armed with Iskander short-range missiles.

They will practice receiving nuclear weapons and deploying them to designated launch areas. The maneuvers will also include air force units that will arm their warplanes with nuclear weapons and perform patrol flights.

Tactical nuclear weapons include bombs, warheads for short-range missiles and artillery munitions and are meant for use on a battlefield. They are typically far less powerful than strategic weapons — massive warheads that arm intercontinental ballistic missiles and are intended to obliterate entire cities.
