40mm榴弾
Generic class-name for any [[grenade launcher]] [[ammunition]], becuase most of the [[weapon]]s have 40mm calibre. Identifiable by the stubby size and rounded tip.
Notable examples are the 40×46 mm LV (low velocity) cartridge used by NATO and US forces, and the Soviet/Russian 40mm VOG-25  for [[GP-25]] series.
