In the late 70s, early 80s, a British company called "Centaur" developed a series of modern half-track vehicles. Soft-skinned, they combined the body of a Landrover 4x4 vehicle with elements from the running gear of the CVR(T) Scorpion light tank. They were in .5 to 1.5 ton class of soft-skin vehicles. They advertised heavily in the defence journals of the day and it appeared to be an excellent idea. They offered superior mobility without much increased cost. As far as I know, they were never adopted by any army.
I believe one of the issues was that the tracks had no return rollers, so when travelling at speed the top of the track flapped up and down at high speed , banging against the body work. The noise this made was unacceptably high (ear damageingly high!)
Not mentioned in the videos is that one prototype was fitted with an Asp-30
30mm cannon during trials.
