What type of pressure is created by the blast of an RPG-7?

The blast from an RPG-7, a type of anti-tank grenade launcher, creates blast pressure. This pressure results from the rapid expansion of gases produced when the rocket propellant ignites and the warhead detonates, creating a violent shockwave. This shockwave generates high-pressure waves that can cause significant damage to both personnel and equipment in the vicinity of the explosion. Blast pressure is a critical component in the effect of explosive weapons, as it is responsible for the immediate physical destruction and the injury mechanism that affects targets close to the detonation point.

While other options might be relevant in different contexts—thermal pressure relates to heat effects, and shock pressure pertains to intense forces generated by shock waves—the primary and most direct impact of an RPG-7's operation is due to the blast pressure created upon detonation.
