Management is as much about convincing people you’re right as it is about getting your way always. Sometimes your subordinates are right and a good manager can still work with that situation. Even in a professional army like the US military there is disagreement and negotiation. This idea that we are all troops in some kind of militia who should blindly follow one person’s will is the bottom half of fascist ideology.
The term "ground troops" was just used as a metaphor for people at the bottom who do a big chunk of the actual work. Every organization would rather have people at least be pro "big picture" vision, and, yes, there should be dissonance and compromise on the "how" we get there part
You can say that but you could also have called them “workers.” Calling them ground troops is intended to evoke the image of people being shelled in foxholes and then running away. It is a bad euphemism that is meant to suggest we are fighting a war. You have to ask yourself—-when someone evokes the imagery of war, do you not think they are spoiling for a fight?
