Come the Colonial Era, the European factions are capable of raising picked bands of Marksmen. These soldiers are a genus of light infantry who like their Archer counterparts are specialised in picking off infantry units from a distance, using their crude yet effective muskets.
In 1700, many European nations did not recruit light infantry regiments. Each line infantry regiment had a light company, but the mass volley was the proper way to employ firepower. As irregular light troops proved their worth and tribal natives refused to co-operate by fighting formal, set piece battles, it was realised that collecting together light companies in ad hoc regiments was no longer enough. Direct recruitment of light infantry regiments began in earnest, and by the end of the 18th Century every army fielded fast, light regiments.
