I'd make it 50NM. 5 is way too easy to bullshit with edge case engineering. Alternatively, set a minimum payload capacity of something like 100kg.
>110 pounds is the minimum payload weight to receive a qualifying score.
Forbidden in 3.7
the key idea is that you need something which can get you onto the enemy position either before hunter drones take off, or that a drone won't take out the whole complement, hence the uselessness of trucks
going on foot is not really due to the human wave nature of the attacks, but rather its like WW1 stosstruppen - they use whatever cover they can find and a squad of 4 on foot is much easier to go through bushes used as cover or when weather is not suitable for flying
of note here is that trucks were not really used for transport on the tactical level on the frontline, however lately (with drones from destinus) logistics runs in the rear have also become a problem even 100km+ deep - thats where the 90% killrate figure comes from
That is quite interesting but in light of that my original question remains (except shifted 100 km back) what about troop transport? Are the combatants suffering a 90% killrate on all their large vehicles near the front or if not then what is special about logistics runs?
They don't. Life expectancy of a Russian on the front line is hours. You just send in another wave.
Edit, I forgot, most are not aware of that:

Given how outlandish the ratio requirement is compared to currently available products I expect this one will be recurring for at least a few years similar to what happened with the self driving challenge 20ish years ago.
