ABERDEEN PROVING GROUND, Md. - To symbolize the shared missions of those in and out of uniform, Soldiers and civilians of the U.S. Army's Test and Evaluation Command, Developmental
Test Command and Evaluation Center stand in shoulder-to-shoulder formation to witness the passing of ATEC colors during a change of responsibility ceremony at the command's new headquarters building Aug. 15.

ATEC Commander Maj. Gen. Genaro J. Dellarocco presided over the ceremony as Brig. Gen. John S. Regan assumed responsibility as deputy commander for evaluation from Brian Simmons, a Senior Executive Service civilian and current executive technical director for ATEC.

The leaders of ATEC umbrella units took part in the unique passing of the colors, which consisted of the AEC colors moving from AEC Command Sgt. Maj. Handy to Simmons to David Jimenez, director of AEC, to Dellarocco, who handed off to Regan, officially charging him with the duties of deputy commander, before Regan returned the colors to Handy.

Dellarocco praised all of his leaders. He said Simmons took charge in 2007 and noted that his technical ability has had a major impact on the command since then. He commended Jimenez, who led DTC for six months before taking over AEC, as being a "mover and a shaker. You couldn't
ask for better experience," he said. And he called Regan "the right man at the right time."

"We'll take it to the next level," he told Regan. "Welcome to APG."

Simmons thanked Dellarocco, Jimenez for their support and his wife who stood by him throughout his 31-year career.

"I leave you in great hands with great leaders," he said to the ATEC workforce.

Jimenez thanked Simmons for his service and added that he felt fortunate to lead the AEC workforce.

"AEC has faced challenges and will continue to do so," he said. "This is just one example of this outstanding organization."

Addressing the ATEC and Aberdeen Proving Ground "Families," Regan called "the beautiful building with the spectacular Chesapeake Bay behind it a fitting background for this event." He thanked the 10th Mountain Division Band for traveling from Fort Drum, N.Y., to provide music for the ceremony, the salute battery from the 22d Chemical Battalion for presenting a Howitzer salute and Dellarocco for providing the opportunity and leadership.

"I look forward to giving you my utmost in my new role as we serve our Army and our warriors in the field," he said.

Adding that the passing of the colors among Soldiers and civilians was indicative of the ATEC organization, he offered his thanks to employees for "ensuring our warriors in the field get the weapon systems they require and deserve."

"We must continue to work together becoming more efficient. I promise to always lead you and to always keep your welfare in mind. This is a great headquarters building for a great workforce
with an important and enduring mission," he said. "I look forward to working with each professional as we serve our nation. Army Strong."
