Guinea holds a 71–29 advantage over Sierra Leone on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (95% of the combined total, $601m) and economic size (GDP) (78% of the combined total, $25.0bn). Sierra Leone leads on logistics & power projection.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
