Interesting touch with the guns being buried underneath him.
Looks like its meant to be guns and barbed wire in Hades. Pretty relevant to the time (and still today).
I found some info on the icon
"Bishop Gorazd of Prague, given name Matěj Pavlík (May 26, 1879 – September 4, 1942), was the hierarch of the revived Orthodox Church in Moravia, the Church of Czechoslovakia, after World War I. During World War II, having provided refuge for the assassins of SS-Obergruppenfuhrer Reinhard Heydrich, called The Hangman of Prague, in the cathedral of Saints Cyril and Methodius in Prague, Gorazd took full responsibility for protecting the patriots after the Schutzstaffel found them in the crypt of the cathedral. This act guaranteed his execution, thus his martyrdom, during the reprisals that followed. His feast day is celebrated on August 22 (OC) or September 4 (NC)."http://byztex.blogspot.com/2014/09/not-often-you-see-nazi-serpent-in-icon.html
