1. A reactive armour wall structure for protection against hollow explosive charge jets, comprising:

  • at least one closed container formed by a separate and replaceable panel structure, and in which a high detonation pressure can be produced,said separate and replaceable panel structure consisting of two mutually spaced and mutually parallel armour walls and mutually spaced armour side walls extending substantially at right angles to said two mutually spaced and mutually parallel armour walls across opposite portion thereof, to define said closed container,an explosive substance filling said closed container and which is detonated by one of said hollow explosive charge jets,said mutually spaced armour side walls having a density greater than 2000 kg./m3 such that said side walls possess high shockwave reflecting properties, and so that detonation shockwaves initiated in said explosive substance in said closed container by the hollow explosive charge jet which propagate in respective opposite directions away from the jet and towards said side walls are substantially reflected by said side walls backing respective reverse directions towards the jet to disturb the jet, the side walls also being made of ductile material and having a thickness and mass such that a product of density and thickness of said side walls is at least equal to a product of density and thickness of said two mutually spaced and mutually parallel armour walls of said separate and replaceable panel structure.
