Soldato (or soldier) is a member of a crime family, and can only be of Italian background. Once a member is made he is untouchable, meaning permission from a soldier's boss must be given before he is murdered. When the books are open, meaning that a family is accepting new members, a made man may recommend an up-and-coming associate to be a new soldier. Soldiers are the main workers of the family, usually committing crimes like assault, murder, extortion and intimidation. In return, they are given profitable rackets to run by their superiors and have full access to their family's connections and power.

The new member usually becomes part of the capo's regime that recommended him. Some soldiers work by themselves, earning money for the family alone though most are part of crews. Sometimes a soldier will be called a button man, because, in theory, when a capo presses a button, someone dies. They are also called made men, who have made their bones, by committing a murder in front of Mafia witnesses or committed a murder on the orders from a high member of the family. This ensures the soldier's reliability: he will never testify against a man who could testify against him.
