[George Moore]

Ok, this may be way off beam.....but tracked transporters were looked at in the UK, some developments including the NLE (Naval Land Equipment) or Nellie, a concept trench digging machine was converted to carry the heavier tanks coming into service....a number of thoughts are raised.....one the development for tank recovery under hostile conditions, or ground that was not suitable for wheeled vehicles.....perhaps, and I was thinking out of the box, with the shortage of rubber after the Japanese had taken large parts of Asia, an alternative was to use tracked bogies.....to reduce the number of rubber tyres required.
Just a thought !!
