M203 Grenade Launcher, which is designed to mount under the barrel of the rifle. It fires 40 MM grenade rounds one at a time, which looks somewhat like an oversized .22 cal short bullet. It would normally be issued to two riflemen in a US Army squad, who are trained to use it and designated as Grenadiers. Sometimes, the squad leader will carry one as well.
