 Gracious God, we thank you for Sergeant Major Mangrel and his committed and faithful service to the 15th Union. Pray for our incoming Sergeant Major Levy as he assumes the post, would you continue to give much wisdom and guide his every steps and decisions. 75. Non-commissioned and staffed non-commissioned officers have carried the non-commissioned officer's sword as the list of leaders of the Marine Corps. The Sergeant Major, as a senior enlisted leader and advisor, is a keeper of traditions for his or her unit. Today's emblematic passive of the sword of office signifies the transfer of the sacred trust from one Sergeant Levy to another.
