The M79 was a single-shot, shoulder fired, break-barrel weapon which fired a spherical 40 mm diameter breech-loaded grenade.
Many different ammunition types were produced for the M79 (and subsequently for the M203), outside of the smoke and illumination rounds three main types emerge: Explosive, Close-range, and Non Lethal Crowd Control.
The M79 has been used extensively also for crowd control purposes (but typically not the M203 as most of these types of rounds won't fit the limited space of the breech break mechanism).
Globular cluster M79 was found by Pierre Méchain on October 26, 1780, and reported his discovery to his friend and colleague, Charles Messier, who determined its position and included it in his catalog on December 17, 1780.
M79 is a beautiful globular cluster at a quite unusual location in the sky: Most globulars are grouped around the Galactic center, but this is one of the few which are situated in the other hemisphere, i.e.
Together with M79, three more globular clusters are suspected to have immigrated from the Canis Major Dwarf: NGC 1851, NGC 2298, and NGC 2808.
