Zambia and Zimbabwe are close to evenly matched, 51–49 on the Relative Advantage Index.
Zambia leads on military spending (72% of the combined total, $406m) and logistics & power projection (53% of the combined total, 10), which Zimbabwe offsets elsewhere.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
