Daily Military Defense & War Archive – US Marines conduct a live fire training on Afghan hills to learn the use of the M203 grenade launcher. An enormous amount of explosive rounds were fired during the training day!


These Marines are firing 40mm grenades from rifle-mounted M203 grenade launchers. The M203’s leaf sites contribute to an effective range of 150-400 meters. This is an extremely fun weapon to fire, as with a little practice, one can learn to “lob in” with increasing arch and accuracy!
