Tanzania holds a 77–23 advantage over Rwanda on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (84% of the combined total, $1.0bn) and economic size (GDP) (85% of the combined total, $78.8bn). Rwanda 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
