L., I think it's more that "today" our hostilities of choice...ahem...require dual-role
vehicles - AFVs that are both practical APCs and infantry section carriers wiv turrets on in the modern battlefield....AND
can be used as impressive "policing" vehicles". Our fault for not picking the right wars...
In reality the British Army left wheeled APCs behind for Western European conditions in the 1980s with the Saxon, a strange four-wheeled throwback - many years after they'd retired the four-wheeled Humber Pig and six-wheeled Saracen from front line duties as APCs....but althought we DID equip a couple of infantry battalions in West Germany with the Saxon, it was mostly used in Northern Ireland on "internal security" duties
IIRC, the logic for multi-wheeled vehicles I.E. six or eight wheelers - in the immediate pre-war period...was their gap-crossing ability
offroad. As WW2 progressed we discovered that while multi-wheel 6x6 or at a pinch 4x4 vehicles DID have some decent offroad capability, the gap-crossing ability offroad wasn't all that was promised - and the tracked
AFV provided this better.
I don't know quite enough about the course of U.S. military vehicle development after about 1950 until the 1980s to comment on that, but the British
experience was tempered EARLY post-WW2 by a need to concentrate as much on the real, actual, happening
"policing" role the Army had to fulfil, with it getting involved in a whole range of post-colonial insurgencies - from Malaya to Northern Ireland by way of Aden, Kenya and a host of others...where the need was for rough road
-capable far more than true offroad ability. Even if the Cold War
British Army had ever gone to war in Western Europe - it would STILL have done so in an environment tamed by two thousand years of farming, road development etc..
"Offroad" wasn't ever
going to mean truly
trackless in Western Europe...
