Yemen holds a 73–27 advantage over Eritrea on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (90% of the combined total, $1.7bn) and economic size (GDP) (91% of the combined total, $21.6bn). Eritrea leads on active personnel.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
