The Principality of Gallia in Valkyria Chronicles 3 is divided up into three sections: the regular Gallian army, the Volunteers who are called upon during emergencies, and Squad 422, AKA “The Nameless.”
Squad 422 consists of members of questionable backgrounds and it essentially a unit that performs “off-the-record” operations that the Gallian army cannot. Its members are known by numbers rather than by name. Valkyria 3’s primary protagonist, Kurt Irving, belongs to this group.
The chap with his feet up on the desk below is Ramsey Crowe. He’s part of the Gallian army, but also appears to be involved with Squad 422 as a senior officer.
