Claim:
An armor module comprising: a rigid casing having a front face, a top casing face defined by first and second transverse edges, said top casing face comprising a surface that is substantially planar between said first and second transverse edges, and a bottom casing face defined by third and fourth transverse edges, said bottom casing face comprising a surface that is substantially planar between said third and fourth transverse edges; and a plurality of discrete cassettes fixedly mounted within the casing, each cassette having a generally flat top base plate and a generally flat bottom base plate, sandwiching between them at least a layer of one of an energetic material and a non-energetic material, wherein for each said cassette said top base plate thereof is defined by fifth and sixth transverse edges and a top cassette face that is substantially planar between said fifth and sixth transverse edges, and said bottom base plate thereof is defined by seventh and eighth transverse edges and a bottom cassette face that is substantially planar between said seventh and eighth transverse edges; wherein the cassettes comprise at least an uppermost cassette, a lowermost cassette and situated therebetween at least one intermediate cassette, and wherein for at least said uppermost cassette and said lowermost cassette, the respective top base plate and the respective bottom base plate thereof are made of metal having the same general hardness; and wherein the cassettes are mounted within the casing such that the top cassette face of the uppermost cassette constitutes said top casing face and the top casing face is inclined with respect to said front face, and the bottom cassette face of the lowermost cassette constitutes said bottom casing face and the bottom casing face is inclined with respect to said front face; wherein each of the plurality of cassettes comprises a front face, each of the plurality of cassettes being mounted within the casing at an acute angle formed between the front face of the cassette and the front face of the casing.
