The RPG's laser can be used to redirect rockets fired from enemy vehicles, an effective method of conserving ammunition for other more powerful targets.Being an explosive, RPG is one of the few weapons that can damage a Gargantua.Intelligent enemies such HECU Soldiers, Alien Grunts and Vortigaunts will try to run away from it, but escaping the blast radius is unlikely, especially if the laser sight is utilized. It can also be used to destroy a large group of enemies with ease, as it has a large damage radius from the point of impact.Land vehicles take usually 3 shots while the Apache takes just 2. The RPG is primarily used to destroy heavily-armored vehicles such as the M1A1 Abrams tank, the M2A3 Bradley armored fighting vehicle and the AH-64 Apache helicopter.An enemy tank is just nearby for Barney to use it on. In Blue Shift, the weapon is first acquired in a HECU cargo truck during the chapter Captive Freight.In Opposing Force, the weapon is first obtained in a box at the vehicle repair garage in the chapter Missing in Action.An AH-64 Apache appears soon after, giving Gordon a good opportunity to test its capabilities. In Half-Life, the weapon is first acquired in a supply cache in the cliff section of Surface Tension.Despite it and its ammo appearing in HECU-controlled areas, such as in the surface areas of Black Mesa, as seen in the chapter Surface Tension, it is not used by NPCs.The user can optionally turn on a guiding laser that directs it to the target. The HECU RPG fires a powerful contact-fused rocket.
