The deviations of the jet of a shaped charge or of the rod of a KE‐round by the flying plates of an Explosive Reactive Armour (ERA) are described by a simple momentum equation. This continuous consideration does not describe the non permanent event at all, as the plates pulsate or act iteratively especially against shaped charge jets. Nevertheless, they give a good trend analysis concerning angles of the ERA‐sandwich changing with respect to the direction of attack, jet or KE‐round velocities and densities of plates or attackers.
