Kelly has held various command and staff positions, to include duty on the Army staff at the Pentagon. He comes to the brigade from the U.S. Army War College in Carlisle, Pa.
In his first address to the brigade, Kelly offered words of inspiration to the Soldiers for the journey ahead.
"The brigade is a very high performance organization. It is already performing at a great level, and I know they will continue on that upward path," said Kelly.
Outgoing leader Eifler commanded the Bronco Brigade for two years as the 3rd BCT Soldiers deployed on numerous joint training exercises.
"We trained hard, played hard and deployed around the world," said Eifler.
"To my staff, past and present, thanks for rowing hard every day. Everything you plan and coordinate must be executed by the Soldiers on this field," said Eifler, expressing his appreciation to the Soldiers who made the brigade better during his time as commander.
"To the Bronco Soldiers on the field, you are our legacy," Eifler continued. "You are our credentials."
Eifler isn't leaving Hawaii anytime soon, as his next assignment is to be the 25th ID chief of staff
