The RP-GG (abbreviation of Rocket-Propelled Goblin Grenade) is an item unique to the Wintergrasp PvP Combat Zone. Friendly workshops will spawn a row of interactable rockets that, when clicked on by a player, will place a stack of five of these items in their inventory. The item's intention is to give a player on foot a weapon to deal with the various vehicles piloted by other players during rounds of combat. It is probably named after the famous Russian rocket launcher RPG-7.
