I have tried to play with the gilden sovereign since he has the "organized" talent. The description of that talent states that armies lead by the sovereign move at the sovereign's speed. I was able to have a sovereign with 5 movement speed (2 from level up, and 2 from items). I have put with him and army composed of NPC with 2 movement speed and 1 movement speed (an escorted noble). Sadly, the army was moving at speed 1.
