40mm Grenade Launchersrnfight Back

摘要

The US Army's programmes for developing two different 25mm grenade launchers - the shoulder-fired XM25 from Alliant Techsystems and the crew-served XM307 ACSW (Advanced Crew-Served Weapon) by General Dynamics -are probably the most ambitious small arms projects in existence. They are meant to revolutionise the effectivenessrnof small-arms fire by detonating HE/ fragmentation grenades directly over the target, thereby greatly increasing the number of casualties, not just of standing men but also those hiding behind cover. Such rounds are known as HEAB (High Explosive Air Burst) or ABM (Air Bursting Munition).
