Ok, i have heard about many of the prototypes for a engineer vehicle. Last i heard was it was stopped due to funding. Grizzly exists as finnished prototypes, ready for series production. Norway built their own ones shown in the movie. Sweden and Netherland has waited and has resently written a contract for a identical vehicle based on a leo 2 chassis. The one u describe sounds as a copy of the old German badger. Still in service in many armys.
The M88 is by the way upgraded and still in service in US. We got a couple museum M88's. Our heaviest tank vehicle. I believed it was a kick to drive one, untill i got my rumpsteak in one...That was so disapointing...even a V12..but nearly no power and guts..
Holy crack when i had my first round in a Leo 2, Thats a mean tank!
By the way, i thought IMI did most work for the Israelis. But i have also heard that they get stuff done by outsiders. Many smart ideas put into some of their modifications. Just look at their house entries vehicle. T-55 without tower, smal powerpack, corridor trough the engine compartement, with dooor at the back to go into houses.
Been some years since i worked with theese babies now...
