The senior Rov of the Ger chasidus where I live told of the experience of the Yom Kippur War in Eretz Yisroel. First, because of the imminent danger, they had a radio set up at the back of the shul with someone posted to listen for call-ups. And as many in the kehila were in the IDF’s chevra kadisha unit (BTW, for those of you who look at the IDF as Tamei, how many militaries have a chevra kadisha made up of chassidim?)They were in shul with their uniforms and left to go to the front the whole day and evening as the call up codes were broadcast.
No one had the chutzpah to throw stones at the Gerrer chasidim leaving in cars, taxis and buses as they could to get to the front.
The approach of these truly ehrlich individuals is being an am kodosh and still being responsible citizens of a Jewish state. Something seems to have been lost in the years since 1973.
