Contemporary
warfare has in fact taken the form of local conflicts, more often than not civil wars, in which no great alliances of nations are involved; these have been wars fought for reasons based in local rivalries, typically inflamed
by historical animosities, ethnic disparity, or religious difference, rather than for reasons of global Realpolitik; they have been fought not with nuclear weapons (or, indeed, other types of weapons of mass - destructive capability) or the latest in military technology, but instead with
conventional weaponry, often of old design, and often limited to rifles, knives, grenades, and light, crew - served weapons which individual soldiers can carry on their persons.
(So clueless are they about modern - day
conventional warfare that they're repeatedly ambushed
by this untrained makeshift militia; they're the Washington Generals to our Harlem Globetrotters.)
