Montoneras

The lands of Spain's colonial empire in the Americas constitute a wholly different arena if compared to Europe, and thus, cavalry traditions developed here are completely different. While the Mexicans may continue some Old World traditions, in the hilly and lush lands of Peru, cavalry warfare however has different concerns - which are addrssed by the existence of Montoneras units.
Montoneras units are not traditional "guard cavalry" units, and are not meant to participate in melee fights against other cavalry units, owing to their lack of body armour. What they do, however, is hunting down and destroying traditional counters of cavalry — that is, heavy infantry and melee infantry. They may be weak, and poorly armed, carrying only lances for their wet work, but it is a task they do very well, being endowed with a strong attack bonus against archaic heavy melee infantry (such as Japanese samurai) and a lesser one when pitted against more modern units, such as Grenadier Guards and Marine Infantry.
