In the same ceremony, Command Sgt. Maj. Mark J. Horn will change responsibility with Command Sgt. Maj. Clinton W. Petty.

Where: Camp Mabry, 2200 W. 35th St. Austin, TX 78703, on the parade field. 

When: Saturday, October 30, 2021 at 1 p.m. Media is expected to arrive no later than 12 p.m. in order to set up before the ceremony commences. Please bring your media credentials. Aris will be available for interviews immediately after the ceremony.  Please RSVP through the State Public Affairs Office via email no later than Friday, October 29 by 3:00 p.m. 

Why: The official change of command is the traditional passing of the colors from the outgoing to the incoming commander symbolically passing responsibility for, and authority over, the unit to the new commander. 

A change of command is a military ritual that denotes a transfer of authority and responsibility for a command. The passing of colors from the present command to the incoming command ensures that the unit and its soldier’s under-no-circumstances are without official leadership. This act alone bonds the new leadership together enforcing a continuance of loyalty and trust to the unit’s soldiers.
