I have created a mod that gives light infantry standard bearers. I always keep light infantry on the line and never use them as skirmishers, and so it has always bugged me that they don't have standards. Standard bearers have been added to all light infantry in the game. Skirmishers such as jaegers and riflemen still do not have standard bearers as they do not fight in a line of battle. The flags in the below pictures are a part of the Napoleon Total Flags 2.0 mod.
Unfortunately I cannot update this mod until a new version of the Pack File Manager is released.

I have two versions of the mod. One has my tighter formation mod built in and the other has vanilla formation spacing. Also, check out my Custom Battle Unit and Faction Unlocker.
