For instance, the French officer pool provided in 1806 I move to Strasbourg and assign a cavalry regiment each to Lassalle and Piston. Lassalle's command envelope and bar graph stats are greyed-out and his name and PWR are in small black lettering. On the other hand, Piston's name and PWR are in white bold and his bar graph stats and envelope are normal. Anf yet there is no discernible difference in their behaviour. What is the significance of this?
