Rabbi Chananya Rachel, a teacher at the Ramat Hasharon and Avinoam yeshivas and an IDF reservist, published a video in which he is seen with his fellow soldiers baking matzahs (unleavened bread) for Passover on the front in Syria. In the footage, the soldiers are seen preparing and baking the matzahs while paying close attention to the details of the halachic law.
In the video, the bakers/soldiers could be heard rushing each other to finish baking within the halachically mandated 18 minutes.
