Which component is involved in displacing reactive armor when the PG-7VR is used?

The component that is involved in displacing reactive armor when the PG-7VR is used is the initial charge. In tandem with the main charge, the initial charge serves a critical function in the operation of the PG-7VR grenade launcher round. Specifically, the initial charge is designed to create a shockwave and a significant energy release upon impact with armor, which is necessary for the displacement of reactive armor systems.

Reactive armor is utilized by tanks and armored vehicles to enhance their resistance to anti-tank projectiles. When an anti-tank round like the PG-7VR strikes such armor, the initial charge detonates first, causing the reactive armor to effectively "react" and blow away from the vehicle's surface. This action is intended to disrupt the projectile's penetration capability and create a safer environment for the vehicle.

The main charge, while responsible for penetrating the target after the initial displacement, is not the component that initially engages or displaces the reactive armor. The fuse's primary role is to initiate the detonation at the right moment and does not play a direct role in armor displacement either. The piercing tip is more relevant to the penetration capability of the projectile rather than the initial armor disruption caused by the initial charge. Thus, it is
