That's a spurious argument.
If transportation nodes are that damaged, than wheels are going to struggle - and you'd still be burning km that you dont need to.
I don't disagree about the HETs, but they are needed anyhow. Wheeled or tracked - you aren't moving after a M-kill and RAEME needs the ability to backload vehicles for heavier repair.

Make a vehicle that can fight and survive and then, using the advantage of speed a B vehicle provides, truck them to the fight.
I find it amazing that people sneer at using HETs to get AFVs that can function to the fight but still don't make Lt Inf walk to the fight....
Except the Brits do it worse than most. Even the US IFV/APC tale seems good compared to British procurement. My favourite quote? It's a “woeful story of bureaucratic procrastination, military indecision, financial mismanagement and general ineptitude, which have continually bedevilled attempts to properly re-equip the British Army over the last two decades”
