A projectile round for intercepting an incoming threat to a vehicle or the like is provided. The projectile round may include an explosive layer, which upon detonation, may cause a the fracturing of one or more material layers into one or both of shrapnel and chaff while simultaneously causing the distortion and/or destruction of a piezoelectric material contained within the projectile round. The distortion and/or destruction of this piezoelectric material may further cause the release of an electromagnetic pulse. The projectile round may be part of a countermeasure system against guided munition threats, including those posed by man-portable air defense systems.
