See but that’s not exactly true. Ships have drone fighter/missiles as a major component and the robot handbook while slanted to regular Traveller/charted space does give the rules, and remotely controlled vehicles have been a part of the cyberpunk aspect in 2300 since the beginning so your not really changing the setting. To quote tools for frontier living “Even on the Frontier, robots and drones are vital components of local economies. Given the chronic worker shortages suffered by most colonies, robots fill in the gaps. They are important in many industries requiring brute force, repetitive work or work in hazardous environments. Robots are commonplace enough that they will be in the background of almost any colony on the Frontier. From crop spiders on industrial farms to Rosies in restaurants, they are everywhere and well-accepted by most, in the same way that appliances and power tools are accepted.” So it’s not a big jump. And I’m talking more about robots than straight drones something that replaces grunts and definitely not something that looks like a human

. Such units would look more like minie tanks that human infantry.
And let’s be honest the Ukrainians are just putting into practice a very old sci-fi concept. Shoot Read the Warbots series by G. Harry Stine that’s a good primer for this.
