RPG isn’t Rocket-Propelled Grenade

Most gamers and those who enjoy learning about military history and weapons are familiar with the phrase "RPG." You can learn that the acronym RPG is frequently used to refer to rocket-propelled grenades by looking it up on Wikipedia. RPG does not, despite what some people claim, stand for "rocket-propelled grenade." That was a backronym we made for a Russian term that already existed in the English-speaking world.

RPG is short for "Ruchnoy Protivotankoviy Granatomet," which is a phrase from Russian. This backronym is rarely questioned because it actually means "handheld antitank grenade launcher," which is essentially a rocket-propelled grenade. But it's similar to discovering that a zipper is simply a name that everyone uses because that's what they're accustomed to hearing, rather than the actual generic name for a thing.
