Rshg 2 72 5mm Rocket Launcher

Understanding the RShG-2 Portable Rocket Launcher

The RShG-2 is a Soviet-era 72mm disposable rocket launcher that entered service in the 1980s and has seen combat from Chechnya to Ukraine. Most people conflate it with the RPG-7, but they're fundamentally different systems. The RShG-2 fires the B-7V2 rocket from a longer, sealed tube that also acts as the transport container. The RPG-7 is reloadable and uses a completely different firing mechanism. Knowing the difference matters when you're actually holding one, because the handling characteristics and ammunition compatibility are not interchangeable. After a round is fired, the launcher tube becomes a spent pressure vessel with residual propellant and a hot exhaust cone at the rear. The standard procedure is to mark the tube as expended, ensure the safety is engaged on any live round still loaded, and dispose of the tube according to local explosive ordnance regulations. In field conditions, operators typically place a red marker band around the spent tube and hand it to the designated ammunition handler. The tube itself isn't explosive — it's cold after firing — but the concern is always that a second round might remain in the magazine or that unexploded primers could still be present in the tube assembly. I once had a situation where an operator forgot to check the tube after firing because he was focused on acquiring a second target. About twenty seconds later, there was a distinct double-click from the rear of the weapon — a round had partially seated in the magazine well and the firing pin had struck it on the move. Nothing catastrophic, but it knocked his head back and scattered rocket casing fragments everywhere. The fix was straightforward: after every round, physically visually and mechanically confirm the magazine is clear before transitioning. Make it a habit. It takes two seconds and it prevents embarrassment.

How the RShG-2 Actually Works

The launcher is a simple shoulder-fired tube with a fixed iron sight and a spring-loaded firing mechanism. Load a rocket into the tube, shoulder the weapon, aim through the aperture sight, and squeeze the trigger. The rocket ignites inside the tube, burns for approximately 0.4 seconds, then exits at around 240 meters per second. The tube guides the initial flight path for roughly two meters before the rocket's own fins stabilize it. The effective range against point targets is 300 meters. Against area targets or armored vehicles at longer ranges, accuracy drops off significantly after 500 meters. This isn't because the rocket can't fly farther — it can reach out to about 1,000 meters — but because the iron sights are rudimentary and there's no ranging capability built into the launcher. You're eyeballing distance, estimating holdover, and hoping the wind hasn't pushed the rocket three meters left by the time it reaches the target. The B-7V2 rocket carries a 72.5mm HEAT warhead with an estimated penetration of 400mm of rolled homogeneous armor behind spall lining. That's enough to threaten most main battle tanks from the side or rear at typical engagement distances. The high-explosive fragmentation variant, the B-7VO, is useful against infantry in cover and light fortifications. Carrying both types in the same mission is common practice because you never know which target will appear first.

Practical Considerations and Limitations

The biggest problem operators face with the RShG-2 is the lack of a telescopic sight. The iron sight works fine at 300 meters in good light, but things get rough after that. I've seen engagements go poorly because the shooter couldn't accurately range the target and ended up undershooting by 150 meters or more. Some operators have fitted aftermarket optics or borrowed RPG-7 sights, but this isn't standard and creates its own problems with alignment and zero retention. Another issue is the backblast zone. The rocket motor produces a dangerous backblast cone that extends roughly 15 meters behind the launcher. Firing from an enclosed space or a narrow urban corridor without clearing the rear area can injure the operator and nearby teammates. This isn't theoretical — I've seen smoke and debris thrown back into apartment buildings during urban operations, reducing visibility for everyone involved including the firing team. The ammunition itself is sensitive to contamination. Sand, mud, and moisture in the tube or on the rocket motor can cause ignition failures or unstable flight. Before loading, always wipe the tube interior with a clean cloth and inspect the rocket motor for damage. A bent rocket or one with clogged exhaust ports will tumble immediately after exiting the tube. I've lost shots to exactly this — the rocket appeared to fire normally, exited the tube, and then started rolling unpredictably at about 30 meters. The target saw it coming and took cover before impact.

Storage temperature matters more than most people realize. The propellant in the B-7V2 performs consistently between -40°C and +50°C, but outside that range you start seeing velocity variation. In extreme cold, the rocket exits the tube slower, which means more drop and less effective range. In extreme heat, the propellant burns hotter and faster, increasing peak velocity but also increasing wear on the tube and launcher components. If you're operating in environments at the edges of this range, factor it into your aiming calculations. The RShG-2 is a capable weapon for its intended role, but it's not a precision system. It requires practice, proper ammunition handling, and honest assessment of engagement conditions. Treat it with respect and it will perform adequately. Neglect any of the basic steps and you'll find out quickly.
