Game-ready Denel Vektor R4 asset, with PBR textures included in the files. This has 14965 polys (26059 tris) and 13614 vertices. As this is a rather old model I repurposed for uploading, normal mesh settings in the Maya native file are set, editing them further might ruin the normal maps included.
Materials in this asset are for the following:
