So there we have a brief overview of the second brigade of Yorcks 1st corps (army of silesia). Ive posted a couple of pictures of the entire brigade in typical attack posture. Note how the fusiliers deploy in front, in line. These are drawn form the regular line regiments. In front of these would be the Freiwillige Jäger detachments. I presume that fusiliers would be the first to reenforce these if needed, followed by the third rank from the musketeer battalions.
