The U.S. is upgrading its missile system with a precision-strike missile that can hit moving targets at sea.

Commonly mistranslated as “rocket-propelled grenade,” it actually means “handheld antitank grenade launcher.” The RPG-2 entered service with the Soviet Army in 1949.

There's the classic bazooka –its official name the M9A1 Rocket Launcher– the RPG-7 anti-tank grenade launcher, the more modern AT4, the Carl-Gustaf M4, and the RPG variants (RPG-32 and RPG-75M).
