Drones & loitering munitions & satellites are, IMO, the 5th major breakthrough in warfare technologies in history. The first was the bow and arrow. The second was explosives. The third was cannons. The fourth was airplanes. The fifth will be Drones & loitering munitions & satellites.
Each breakthrough advanced the measure of the "stabbing" action occupied in 4-dimensional space-time and the intensity of the action. For the simple knife, the range of attack-in-space was arm's length and there was only one direction the attack could come from. The intensity of the action was almost non-existent. Very few "stabbings" per unit of time were possible with arm strength.
--------------------------------------------------------------------------------------------------------------------------------------------
1) The the range of attack-in-space increased little bit thanks to the spear and sword, but other characteristics did not change. When the bow and arrow were invented, the range of attack-in-space was now tens of meters. This was the first breakthrough.
2) When explosives were added, the number of "stabbing" per unit of time, in other words, the intensity of the action, became almost uncountable. For example, with the explosion of a barrel of gunpowder, the "stabbing" action could be performed hundreds of thousands of times instantly.
3) When cannons came, the range of attack-in-space increased greatly. Now it was possible to "stab" the enemy from kilometers away.
4) With airplanes, both the range of attack-in-space increased to hundreds of kilometers and the directions from which the attack could come became diverse. Unlike cannons, the "stabbing" move of an airplane could be possible from any direction. The only problem for airplanes was that the range of attack-in-time was small. The airplane could not prolong the duration of the threat because it could not stay in the air continuously.
5) The problem of continuity of the threat has begun to be overcome with drones & loitering munitions & satellites. The "stabbing" threat produced by these vehicles is 3-D like airplanes and also range-in-space is not inferior to airplanes. However, unlike airplanes, drones & loitering munitions & satellites can prolong the duration of the threat. For example, a TB-3 can stay in the air for days. An FPV drone can land at a high point and wait for its victim like a mine for days. Satellites are always up there anyway.
