Right in almost all cases, but what about The Intrepid GdD Rapp, ADC of Napoleon, in the period from 1800 until 1814 from time to time ADC of Napoleon
As such, at Austerlitz, he was sent to lead some cavalry of the Imperial Guard, including the splendid Mamelukes of the Guard, in a charge against the Russians, which broke the Russian Imperial Guard
At Schleiz and Jena, Aspern-Essling and Wagram, he served as ADC again, even when he had the rank of GdD.
The same at Borodino, where he took command of Compans' division after Compans was wounded, and received his own wounds.
I don't see Rapp as a ball-leader for Napoleon, as he fell into disfavor for his outspoken disapproval of Napoleon's divorce from Josephine.
