Light infantry on domestic terrain doesn't need anything like those sorts of ratios. Chechen militia in the first Chechen war defeated the Russians well enough to win independence without any sort of logistics ratio like that on the military side, as did the YPG light infantry that defeated ISIS and held off the Syrian military well enough that they basically truced or better.

Higher ratios might be needed to project power to outside borders, but for defense within the territory they can be combat effective against many possible forces with small ratios of military side logistics.
