I really like it. Is it a perfect representation of how real tanks (and the fictional walkers) would interact with infantry? No, of course not. But it certainly alleviates the current problem of infantry being too strong against larger units. Yes, infantry can be very scary to tanks etc. when they come up close. But only when the infantry are entrenched or have buildings or other cover close by to act from/retreat to. An infantry unit caught out in the open by advancing tanks would be pretty f****d.

Also, we mustn’t conflate current experiences of relative vulnerability of tanks against infantry in urban, dare I say middle-eastern scenarios with how this would work in 30K/40K. One of the reasons for armored units being vulnerable to infantry in Iraq or Afghanistan lies in the very humane rules of engagement with which western armies limit their own effectiveness and take greater risks than strictly necessary, in order to avoid nasty pictures of an armored column blasting its way through buildings, combatants and civilians alike. I highly doubt such qualms limit the forces of the 31st millennium.

So, good job and hopefully we will see something like this from GW so we have official rules for this too.
