In addition, bunker design was arranged in "series", the 1939 designs with A and B thickness falling into the 100 series. Later 400, 500 and 600 series were created, the new series were more designed to enable the casemate to be capable of taking captured weapons than to be stronger, the 400 series was designed for Czechoslovakian weapons.

Bunkers deflect the blast wave from nearby explosions to prevent ear and internal injuries to people sheltering in the bunker. While frame buildings collapse from as little as 21 kPa (3 psi ; 0.21 bar ) of overpressure , bunkers are regularly constructed to survive over 1,000 kPa (150 psi; 10 bar).
They were called Hochbunker (literally, "high bunkers"; better translated as "above ground bunkers", to distinguish them from the usual deep i.e. underground air raid shelters) and those that functioned as anti-aircraft artillery platforms were also called Flak towers. Some were over six stories high; several survive to this day because of the ...

In Flossenbürg and elsewhere, the Schutzstaffel built forced-labor camps where prisoners of the Third Reich were forced to mine stone and make bricks, much of which went directly to Albert Speer for use in his rebuilding of Berlin and other projects in Germany.
Four type M272 regelbau ("standard design") casemates requiring 600 cubic metres of concrete and four tons of reinforcing steel were built, with walls and roofs over 2 m (6.6 ft) thick. Each casemate held a 15 cm TbtsK C/36 naval gun , manufactured by the German-controlled Škoda Works in Plzeň , Czechoslovakia , with a range of approximately ...
