Serbia holds a 84–16 advantage over Montenegro on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (94% of the combined total, $2.8bn) and economic size (GDP) (92% of the combined total, $90.1bn). Montenegro 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
