Gas Mask in the Yom Kippur War

During the Yom Kippur War, Reb Efraim Mol was stationed at Israel's southern border with Sinai, when intelligence came in about a possible imminent chemical attack by the Egyptians. Ordered to shave his beard in preparation to don a gask mask, Efraim convinced his superiors to allow him to consult the Rebbe first.
