The "Training Officer" trait says that these guys "If the commander, will train up to two regiments of conscripts to regular soldiers every turn".
So I sent one these leaders to a spot with a bunch of conscripts, put him in his own stack with them, and nothing seems to be happening. (4 turns and not a single conscript upgraded yet.) So I am thinking it is a die roll, and maybe I am unlucky; but to test it I load up the same officer in a later war scenario. In this scenario the same leader trains consistently either 1 or 2 conscripts per turn, every turn so far.
So I was wondering if there is a die roll for the chance or could the leader be flawed in one scenario? See the attached for the stack the leader has been sitting in now for 4 turns with no change.
