von P: it is an eastern front thing. a close friend while serving as Waffenmeister in his company/regiment came up with several useful designs with both Panzerscreck as well as Panzerfaust, some of the trip wired. the carriage though seems only photographed in Berlin were also used in other "larger" eastern cities in Germany for the self defense mode against Soviet armor.

Crazy: another book that I thought of and maybe a few of our members have the book as well, the same chap that wrote Tigers in Combat 1 and 2 also wrote about the heavy tanks in Das Reich which also carried over to the Schwere SS Panzer Abteilung 502 which served on the Ost front east of Berlin and south of it during 1945 with the heavy Königstiger so that monster book you may want to seek ?
