Yes, one size offset (63mm).
The military Hutchinsons are forged and lighter than the civilian version.
The Ashtaroth wheels are cast, not forged, and the military/armored version is stronger as well. It is slightly heavier 12.9 vs 13.8 kg as shown earlier. I have both versions of the 16" Ashtaroth wheel, so this is first hand info.
The 18" Ashtaroth comes in 2 versions as well. The ET of 43mm and ET 63mm. I assume the 63mm offset version is lighter as the 20mm difference in offset is achieved by the increased thickness of the solid aluminum backing
