Warfare is fundamentally about breaking the enemy’s will to fight. This can be done with violence, or without it – before the fight even starts, through raw intimidation. Working from this understanding, military theorists have divided the history of warfare into five generations.
First Generation Warfare, abbreviated 1GW, was war as it was waged from the dawn of civilization up through roughly the Civil War. This style of conflict involved massed line infantry, equipped with spears, pikes, swords, or line-of-sight ranged weapons such as longbows, crossbows, or muskets. The basic tactic was to draw up two large groups of armed men, bring them into close contact, and have them hack at one another until one side grew demoralized by the slaughter, at which point their line would break and the real slaughter could begin.
Industrial or Second Generation Warfare (2GW) brought rifled firearms, machine-guns, and indirect artillery. Men could now be killed at a great distance, without ever seeing the enemy. Camouflage, concealment, and cover became the keys to victory. Its heyday was roughly from the Civil War to the Great War.
Mechanized warfare or 3GW arrived with the internal combustion engine and powered flight. Tactics now depended on speed and manoeuvrability. It dawned with the Second World War and reached its apogee with the invasion of Iraq.
Mechanized warfare created an overwhelming advantage for large industrial states. Small states and non-state actors responded with 4GW, which can be thought of as televisual warfare – combat via propaganda. This is war as fought with cameras and media distribution networks. It is guerrilla warfare via weaponized morality: using the enemy’s own military actions against it by showing the consequences of war for one’s civilian population to the enemy civilian population. Bait the enemy into killing babies, then ask them how many more babies they’re willing to murder. Think Vietnam, Afghanistan, Iraq.
The response to 4GW is 5GW – warfare by psyop, utilizing misinformation and sentiment engineering. Its characteristic weapons platform is the social network. Where 4GW seeks to use the enemy’s own morality against it, 5GW seeks to change that morality, to transform the enemy’s inner nature, getting the enemy to attack themselves for you, to surrender with open arms and smiles on their faces … ideally, without the enemy even realizing that they’re under attack.
