Initialism. When applied to a "rocket-propelled grenade" it derives from Russian РПГ (RPG), initialism of ручно́й противота́нковый гранатомёт (ručnój protivotánkovyj granatomjót, “hand-held anti-tank grenade launcher”), of which "rocket-propelled grenade" is a backronym (though an accurate description of the weapon system).
