The regelbau 610 is a ‘Gefechtsstand für eine verstärkte Kompanie oder für Batterieoffizier’. It is essentially a command bunker with radio equipment. In Widerstandsnest 311 it was used to send out the commands given by the Führer der Schnellboote staff. It is built mirrored from the original plan in the typology. Just like the V149, it had the luxury of central heating throughout the entire bunker.
