The war-wide military allocation is a broad visualization estimate rather than a surviving count.

Figures are working historical estimates and vary across sources. Labels identify totals that are reported, disputed, or unknown; numerical allocations may be retained for comparison without implying exact knowledge. Each number represents human lives, not false precision.
