Description
The R621, originally designated as the R501, was a standardised infantry squad shelter constructed by Nazi Germany as part of the Atlantik Wall coastal defence system during the Second World War. Designed to accommodate a single infantry squad—typically up to 10 soldiers—it provided protection against artillery fire, aerial bombardment, and harsh weather conditions.
Built from reinforced concrete, the R621 featured a single entrance with a gas-tight door, an air filtration system, and internal fittings such as bunk beds, weapon racks, and storage space for equipment. Its compact layout allowed for rapid construction and integration into defensive networks near gun emplacements, observation posts, and command bunkers.
The redesignation to R621 reflected minor structural improvements and standardisation across occupied territories. These shelters enabled troops to remain close to combat positions while maintaining readiness and survivability.
This model has a removable roof and/or floors for access.
Please note that these are designed to be built into terrain, gaming boards and so can be quite deep – please contact us if you require them to be lower to the tabletop and we will shorten them before printing to save material and cost for you.
