[1][2] There are five generations of warfare: In 1648, at the end of the Thirty Years' War, the Treaty of Westphalia gave a practical sovereignty to the German states, which until then were semi-independent components of the Holy Roman Empire.
[3] Alternatively, it has been argued that the Peace of Westphalia did not solidify the power of the nation state, but that the Thirty Years' War itself ushered in an era of large-scale combat that was simply too costly for smaller mercenary groups to carry out on their own.
Because these technologies were adopted gradually throughout the Americas and Europe, the exact end of the first generation of modern warfare depends on the region, but all world powers had moved on by the latter half of the 19th century.
Second generation warfare still maintained lines of battle but focused more on the use of technology to allow smaller units of men to maneuver separately.
The development of the blitzkrieg highlighted some of the flaws of static firing positions and slow-moving infantry, so this can be considered the beginning of the end for the second generation, at least as the dominant force in military strategy.
The second generation saw the rise of trench warfare, artillery support, more advanced reconnaissance techniques, extensive use of camouflage uniforms, radio communications, and fireteam maneuvers.
[10] In 2008, the term was used by Terry Terriff,[11] who presented the 2003 ricin letters as a potential example, but stated that he was not entirely sure if it was a fifth-generation attack, claiming "we may not recognize it as it resolves around us.
Rees described the nature of fifth generation warfare as difficult to define in itself, alluding to the third law of science fiction author Arthur C. Clarke – "any sufficiently advanced technology is indistinguishable from magic.
[15] On the contrary, Thomas P. M. Barnett, believes that the effectiveness of fifth-generational warfare is exaggerated, as terrorism conducted by individuals, such as Timothy McVeigh or Ted Kaczynski, lacks the support of more organized movements.
This was seconded by George Michael, who noted that in the United States, gang violence was responsible for far more deaths than lone wolf terrorist attacks.
