Militia

Militia (AKA Recruits or Swordsmen) are the lowest type of unit class and most of your units will start as this class, there are exceptions, because some new commanders may have an unit pre-specified.

They can be upgraded to either Infantry, Archers, or Pikes for 6 coins. This action can't be reverted.

They are the weakest type of unit you can have, and are weak against most enemy units. Any enemy unit other than Archers (in melee combat) and Militia will pose a major threat to your Militia.

Strengths

 * Perform well enough against Archers (in melee combat) and Militia.

Weaknesses

 * No shields; this makes them vulnerable to most attacks.
 * Slower moving than upgraded units, poor melee initiative and trip more often.
