I would like to see a new tech, along the military line, that would allow the construction of "Special Forces" modules. These modules would only carry 1 legion of troops, all "elite deep-space trained comandos". When equiped to a ship, it would allow the ship to transport these Special Forces to AI-controlled starbases and mining constructs.
When moved to intercept, instead of ship-to-ship attacking (and complete destruction of the base), the SF would move out and we would see a interior battle similar to a planet-side battle. If successful, control of the starbase would change, with or without damage to the modules on the base.
This could even lead to a new tech branch of related invasion tactics.
