item_weapon_rpg
item_weapon_rpg is a point entity available in 
Black Mesa.
It is rarely used by the HECU and it is used by the player to take down Apache Helicopters and Abrams tanks. It also is used to take down Lavs. It is also effective at blowing up groups of enemies as well. Giving the player an RPG at the beginning may not be the best idea because it doesn't balance difficulty.
