experimental weapons systems like OICW

[Mobhack]

try unit No 747 (cavalry scouts)

That is I think the "OICW" - split into the 2 game components, rifle and G/L. Weapons 81 and 82, and unit vision 20. Those units are probably "what-ifs", as the thing has not been fielded, and could be canned/changed/delayed whatever as with any future system.
