Sorry I should have been more careful about those versions They are indeed all M113A4 versions but the two latter ones are not baseline M113A4s but special purpose M113A4s As such they don t belong there agreed I will edit them out The Saad however is a baseline M113A4 variant The slopes on the upper backsides roof are a minor design change of the hull you may call it cosmetic the rest of the whole vehicle is still an M113 Roadwheels idlers chains lights etc are all 1 1 exchangeable with any given M113 Licensing is not an issue a copy of an M113 is still an M113 The M113 is not a brand bound to a specific company but a military design and it doesn t matter much who builds it The Egyptian EIFV and other M113 variants are also built in Egypt indigenously and so are the Turkish variants made by FNSS
