Using the laser rangefinder and digital sights, the operator programs the 20mm grenade to explode at a certain distance, such as airbursting over enemy foxholes. Unlike its magazine fed American and Korean doppelgangers, the ZH-05's lighter single shotgrenade launcher makes it easy to switch between mission specific ammunition during a firefight. That's the same idea behind the ubiquitous M203 grenade launcher slung under American M-16 rifles. More importantly, Chinese 20mm smart grenades are superior to their American and Korean counterparts, since the single purpose grenades have smaller electronics, and thus more payload space. Currently, there are three 20mm grenades for the ZH-05; an anti-personnel airburst grenade, a shotgun style canister grenade and an anti-material impact grenade. The canister grenade, which directs a spray of lethal pellets, has received praise from Chinese troops as a "long range shotgun". The canister grenade could also be a nifty way to shoot down small enemy quadcopters and UAVs.
