remember France had to wait a long time to catch up in artillery design, well Gribeauval was certainly inspired by the Liechtenstein system.
The Austrians, by the way stress already in the 1757 regulations that the artillery is an independent branch of arms, that all 3 branches of arms had to work closely together and introduced an artillery commander who had to be incorporated in the decision making. Of course when one is reading only French sources, as good as they are, one is missing out the complete picture and what happened in other nations as this time.
