paragraph_text: World War I
  
  An important feature of industrial age warfare was technological escalation – innovations were rapidly matched through replication or countered by another innovation.
  
  World War I marked the entry of fully industrialized warfare as well as weapons of mass destruction (e.g., chemical and biological weapons), and new weapons were developed quickly to meet wartime needs. The technological escalation during World War I was profound, including the wide introduction of aircraft into warfare and naval warfare with the introduction of aircraft carriers. Above all, it promised the military commanders independence from horses and a resurgence in maneuver warfare through the extensive use of motor vehicles. The changes that these military technologies underwent were evolutionary but defined their development for the rest of the century.
