Col. Charles D. Costanza and Command Sgt. Maj. Michael D. Green assumed command and responsibility, respectively, of the 3rd Armored Brigade Combat Team during a ceremony May 17 at the National Infantry Museum Parade Field.

The colors were passed by Col. Johnnie L. Johnson, Jr., the outgoing commander, and the NCO's sword was passed by the brigade's former command sergeant major, Command Sgt. Maj. Brian D. Harrison.

The reviewing officer, Brig. Gen. John H. Hort, 3rd Infantry Division deputy commanding general (rear), congratulated the outgoing command team on a job well done, highlighting the brigade's recent training cycle at the National Training Center and deployment to Kuwait.

"It is an honor for both Command Sgt. Maj. Green and I to have the opportunity to serve with each and every one of you," said Costanza to the Soldiers of the Sledgehammer Brigade. "Thank you for your service and dedication and your sacrifice. Thank you for teaching us how to lead and for teaching us what selfless service is all about."
