Militia are the basic troops you start with. They are not formally trained but are armed with a desire to preserve their new life in Vinland and an iron will won in the flight from the Devourers. Poor versus ranged troops, they can be effective against Light Cavalry. Upgrade their equipment to get the best out of them; even a Falchion and a Kettle Hat give them an edge in battle.
You can upgrade your units by researching new equipment.
The higher is the equipment's level, the higher are your units damage, health and carry capacity. Beware that some upgrades may lower capacity and speed.
