The M79 'Bloop Tube' was a post-WWII development intended to provide infantry with a portable, accurate grenade launcher, replacing the bazooka. Its core innovation was the 40x46mm low-pressure system, adapted from German Rheinmetall High-Low pressure technology, enabling a lightweight design. Despite its success in Vietnam, its single-shot nature led to the development of under-barrel launchers like the M203.

This review covers the Milkor M32 and M32A1 40mm rotary grenade launchers. The M32 features a 12-inch barrel and fires low-velocity rounds, while the M32A1 has an 8-inch barrel and can fire both low and medium-velocity rounds up to 800 meters. Both are semi-automatic, six-round capacity launchers with unique loading and aiming systems designed for the ballistic arc of 40mm rounds.

The Mk18 Mod0 is a hand-cranked 40mm grenade launcher developed in 1962 and used by the US Navy during the Vietnam War, primarily on patrol boats. Despite being considered obsolete upon introduction, its reliability and simple operation, featuring a split-breech mechanism and a unique Dacron belt, made it a favored weapon for close-range engagements up to 250 yards. It fired low-pressure 40x46mm rounds, offering a practical rate of fire between 100-200 rounds per minute with an impressive average of 5,000 rounds between stoppages.
