“ The grenadier companies were formed always of the most powerful men in the regiment and, when the grenade ceased to be used, they maintained their existence as the “crack” companies of their battalions, taking the right of the line on parade and wearing the distinctive grenadier headdress. This system was almost universal, and the typical infantry regiment of the 18th and early 19th century had a grenadier and a light company besides its “line” companies. ”

“ In the Prussian service the grenadiers became permanent and independent battalions about 1740, and the gradual adoption of the four-company battalion by Prussia and other nations tended still further to place the grenadiers by themselves and apart from the line. ”
