This vehicle was made in 1985 as a private venture by CMI (now John Cockerill) after they had finished designing the CM 90 turret and wanted to present it to the export market.

CMI then bought a Belgian M113A1-B and fitted it with the CM 90 turret, making it a fire support vehicle still capable of carrying 10 passengers and flotation panels have been attached so that the vehicle remains amphibious.

The M113 hull is very well known, being made out of aluminium and isn’t really supposed to take heavy anti-tank fire. The turret as well is very light, but unlike the hull, is made of welded steel, and while additional armor can protect it frontally from 14.5 mm AP fire, base armor protection will only get you as far as 7.62 mm from all angles.

However armor isn’t everything, and the turret features a good 90 mm Cockerill Mk III cannon firing HEAT-FS shells penetrating up to 330 mm of armor, as well as a variety of HE, HESH and smoke shells. No APFSDS yet, that’s for another slighty later version of the same vehicle.

Optional equipment include a ballistics computer, night vision (no thermals) and a laser rangefinder.

No major redesigns have been made to the hull, and the mobility remains pretty good, although the turret does bring the vehicle to its maximum weight.

Other features include 2 machine guns including a pintle-mounted one, 16 smoke grenade launchers, x8 magnification for the gunner and commander sights and electro-hydraulic traverse and elevation.

In-game, this could perform very similarly to the C13 T90 in the Italian tree with it having the same gun with better shells but also worse armor somehow.
If it does get the optional laser rangefinder, it could suffer from the increase in BR since it doesn’t have a stabiliser and chemical rounds may start to become problematic.

Overall i think this could be a slightly worse C13 due to its worse hull, but it could definitely still be fun!

As for where it would go, i’d personally want to keep this for a Benelux tree, as Belgium is its only possible operator nation, but in the event of a Belgian subtree to France, then France is the next most logical option to me.

Let me know what you think!

Very ugly but interesting vehicle, +1. I’d think it’d be best at 6.7 without LRF or 7.3 with, being a slightly less mobile, higher profile C13 or IKV 91.
