Austria holds a 68–32 advantage over Serbia on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (70% of the combined total, $6.4bn) and economic size (GDP) (86% of the combined total, $535bn). Serbia 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
