Enemy of an enemy
In the entire Milky Way galaxy, all robots from the SCS empire had their remote connection disrupted for exactly 12 minutes. The seemingly small duration of time resulted in incalculable financial and strategic losses for the SCS empire, not only changing the flow of countless battles, but resulting in them losing various opportunities.
Earth alone was able to completely change the flow of ongoing battles within those 12 minutes. Even if the robots regained their ability to connect remotely, it did not matter for almost every robot they had deployed on earth and been destroyed within that period. Although that would not, in any way, change the final outcome of the war, it had bought humans some valuable time.
