I disagree, I think there should have been more things with the idea of Radio Silence in the game. There should be more ways to play against your opponent than with combat alone. Arguably the mistake in execution however is that this is a global ability that -currently- doesn't have any drawbacks or requirements. Panzer Elite's Vampire Halftrack and the way it could steal resources back in CoHOF is a better implemented example of a "4 dimensional chess" ability.
Those are totally different things.
The Vampire Halftrack is a clever unit design where you hide it to steal resources. The opponent knows it's there and needs to find it. It interacts with the mechanics
in an unusual way.
Radio Silence is "your opponent has bad UX for a minute." It's in the same camp as "randomly rebind your opponent's hotkeys for a minute" or "your opponent gets input lag for a minute" or "randomly adjust your opponent's headset volume." These designs are so rare for a reason: their purpose is solely to frustrate the opponent, which isn't what you want if your game to be enjoyable.
I do like the idea of freeing up a slot for the Sturm Offizier. That unit needs to be in more doctrines and it'd fit the theme well enough.
I could completely get behind replacing Radio Silence with Sturm Offizier.
