Ukrainian troops were recorded using a Milkor M32A1 40mm multi-shot grenade launcher in combat, and the American-made weapon system was likely delivered in the most recent batch of US-delivered military aid.

The M321A1 is a hand-held, gas plug operating, semi-automatic, revolving action, 40mm Multi-Shot Grenade Launcher (MSGL) that can fire all six rounds in three seconds. Its maximum range is between 400 and 800 meters, depending on the type of rounds used.
