Geuzen Raiders

Melee infantry, weaker than Halberdiers, but can entrench themselves if idle for five seconds. Transports carrying them are tougher and faster when travelling through water.
Their main draw is that they are very powerful when used to defend against cavalry. Not only can they lock together to defend against enemy cavalry, they are capable of causing splash damage in melee. It is thus better to counter them, using artillery or Musketeers once you have them ready.
