Great, that we got that straightened out
According to the book, the Siemensstadt Batallion 3/115, was well equipped and uniformed:
HQ company of 200 men
-3 x Rifle companies each of 150 men armed with French rifles and MG42s
-Heavy weapons company with 2 inf guns ( platoon 1), 4 heavy mortars (platoon 2), 2 heavy -machine guns (platoon 3)
-Gun company with 4 Russian 152mm howitzers and a 220mm French mortar
All officered and staffed by Siemens employees, of which several WW1 veterans, except the Heavy and Gun companies which also included specialists from Police and Wehrmacht units. In total 770 men. The unit saw heavy fighting in Berlin April 21-May 2 being almost annihilated, receiving 26 Iron Crosses.
There was also a Reserve Batallion no 3/132 with 480 men but without equipment and weapons supposed to defend the Siemensstadt area.
I see some potential here for some "Weird War" influences with a Siemens flag and employees in their factory overalls with The Siemens logo. I wonder if the type of "mono" overalls used by SCW Asaltos could be somewhere near a potential dress for a Siemens factory worker?
