REDSTONE ARSENAL, Ala. — Brig. Gen. Jason Jefferis assumed command of the U.S. Army Security Assistance Command during a June 1, 2026, change of command ceremony on the Army Materiel Command Parade Field.
Lt. Gen. Christopher Mohan, commanding general of AMC, hosted the event.
Mohan transferred the USASAC colors from Outgoing Commander Brig. Gen. Allen Pepper to Jefferis during the ceremony. The passing of the colors is a time-honored military tradition that symbolizes the passing of responsibility and authority from an outgoing commander to the unit’s new commander.
During his remarks, Mohan recognized the USASAC workforce and its critical foreign policy impact on partnership building. He thanked Pepper for his superior leadership and welcomed Jefferis to the command.
Jefferis said he is “humbled to join a world-class team of experts that has spent decades mastering the intricate world of foreign military sales and security cooperation.”
“Having seen the impact of your collective efforts from an operational standpoint, I have a deep appreciation of just how critical this mission is,” said Jefferis. “Through my tours of assignment in Iraq, Afghanistan and around the globe, I know firsthand what happens when our allies have the right equipment and the right training, at the right time. That experience gives me a profound awareness of the delicate balance of policy, diplomacy, and logistics that you all master each and every day, where every decision carries significant weight for our nation and our partners.”
Jefferis described his role as a bridge-builder and champion for USASAC. “I will bring every ounce of my energy to support you as we support our allies, because their security is our shared success,” he said. “To the greater Security Assistance Enterprise, I ask you to join me. Let's laser focus on the mission, innovate our systems and processes, and reaffirm our commitment to strengthening our partnerships at home and around the globe. Let's demonstrate the unbreakable strength that comes from standing together.”
Mohan also highlighted USASAC’s record-breaking FMS growth under Pepper’s leadership--$42.8 billion alone in new business in 2024--the largest annual total in the command’s history.
“His most strategic impact has been profound--$34 billion in modernization for European partners, $11 billion in precision fires package strengthening INDOPACOM deterrence, and major armored and missile defense improvements across the Middle East,” said Mohan. “Allen, your leadership has been outstanding, and your influence will be felt for years to come.”
During his remarks, Pepper thanked the USASAC workforce, SAE leadership, and friends and family for their dedication and support. He told the workforce that he regularly received excellent feedback from Geographic Combatant Commands, Army Service Component Commands, and partner nations—proof positive of how important and appreciated their work continues to be.
"I can assure you that it has been a tremendous blessing for me to have had the opportunity to command USASAC," Pepper said, describing FMS as the centerpiece of the nation’s foreign and defense policies.
USASAC leads the AMC Security Assistance Enterprise and develops and manages security assistance programs and foreign military sales (FMS) cases for the U.S. Army. The command currently executes a $327 billion FMS portfolio with more than 133 nations and 11 agencies.
