“Lieutenant General (Ret.) Walker has spent decades tackling some of the most complex logistics challenges in the U.S. military,” said Jon Garrity, CEO of Tagup. “As he joins Tagup’s Advisory Board, his perspective will sharpen how we build and scale our technology to deliver measurable readiness gains across supply, maintenance, and mobilization—especially for operations in contested environments.”

LTG Walker brings decades of senior leadership experience overseeing large-scale Army logistics and sustainment operations, including serving as the Deputy Commanding General of the United States Army Materiel Command, where he was responsible for enterprise-level logistics, readiness, and force support. His career has been defined by ensuring warfighters have what they need, when and where it matters most. This operational perspective strengthens Tagup’s mission to apply AI to logistics at enterprise scale, particularly as the U.S. military modernizes logistics operations for the modern, contested battlefield, where scale, speed, and adaptability increasingly define logistics success.

“Logistics determines whether forces are ready or not; there’s no margin for error,” said LTG Donnie Walker (U.S. Army, Ret.). “I’ve spent my career focused on sustainment and readiness at scale, and that challenge is only getting more difficult. Tagup is building the kind of decision advantage logisticians need: software that can reason under constraints, move at operational tempo, and improve readiness outcomes. I’m proud to join the Defense Advisory Board and support the team’s mission.”

Walker’s appointment builds on Tagup’s already distinguished Defense Advisory Board, which brings together retired flag officers across branches of service who have commanded, modernized, and sustained forces at the highest levels. The Defense Advisory Board includes Lieutenant General Brad Webb (U.S. Air Force, Ret.), Lieutenant General Neil Thurgood (U.S. Army, Ret.), and Rear Admiral John Neagley (U.S. Navy, Ret.), all leaders with deep expertise spanning logistics, operations, acquisition, and force readiness.

The Defense Advisory Board provides strategic guidance grounded in real-world operational experience. This expertise helps ensure Tagup’s AI solutions are deployable, trusted, and aligned with the realities of modern warfare, including contested supply chains, limited data visibility, and urgent decision timelines.

As the Department of War increasingly turns to AI to improve sustainment and readiness, Tagup continues to align advanced technology with the experience of leaders who understand what is at stake when logistics fails and what is possible when it succeeds.
