Would tracks have improved Grillo's obstacle crossing?

Would Grillo have been more useful with tracks instead of chains?

Possibly, but no comparative result is given; the chains were chosen because trials showed they worked, although they were noisy.

Tracks are suggested as a possible improvement on Grillo's chains. They could make the design more interesting, but no tested performance comparison is offered. Chains had been selected because they were expected to work, and trials confirmed that they could cross the obstacles. Their practical limitation was noise during an attack.
