After 10 years as an Army infantry officer in airborne and special operations organizations, Garrett Ewanouski knew firsthand how difficult it could be to keep people, plans, and information aligned across distributed units while operating under ambiguous conditions. As he prepared to leave the Army, a seven-week internship at Onebrief through the DOW SkillBridge program gave him the opportunity to put that operational perspective to work in defense tech.

Today, Garrett is a Partner Delivery Manager on Onebrief’s Global Delivery team within Customer Relations, where he supports military customers and helps improve how users learn and adopt Onebrief.

Looking for a Tangible Way to Contribute

Garrett commissioned as an infantry officer in 2016 and went on to serve in a range of leadership and staff roles, including as a company commander in the 75th Ranger Regiment. Those assignments gave him a practical understanding of what military staffs need from technology and prepared him to learn quickly as organizations, priorities, and conditions changed.

“I’m really passionate about national defense and strategic deterrence,” Garrett said. “I wanted to contribute in a tangible way and help our forces have the best tools and capabilities for potential future conflicts.”

Garrett already understood how SkillBridge could support military transitions. As a company commander and through his work in battalion personnel roles, he had reviewed and approved SkillBridge requests for other service members. When his own transition approached, Garrett sought general advice from a former battalion commander who had recently joined Onebrief. Through that conversation, Garrett learned more about Onebrief and discovered a SkillBridge opportunity aligned with his military experience and interest in defense technology.

As Garrett researched Onebrief, he recognized the kind of opportunity he had been looking for: work connected to national defense and focused on giving military teams better tools to solve complex and dynamic problems. The internship fit the practical needs of his transition, but Onebrief’s mission was what drew him in.

Learning Onebrief From Multiple Angles

Garrett spent the first part of his internship learning alongside the Global Delivery team. Because he remained on active duty, he built context through internal meetings, product training, and insights from the team rather than direct customer engagement. This showed him how Global Delivery works to understand the challenges military staffs face and help customers apply Onebrief to solve them.

From there, Garrett moved into Product Operations, where he supported research, testing, and evaluation for Arbiter—Onebrief’s command decision platform, which unites agentic AI planning, continuous automated wargaming, and a shared collaborative workspace to help commanders decide faster and better before execution begins.

The range of Garrett’s experience allowed him to see how different parts of Onebrief connect. He moved from learning how the product reaches customers to exploring how operational needs inform research, how new capabilities are tested, and how feedback helps teams refine the product.

During an internal testing effort involving several teams, Garrett helped coordinate the sessions and turn participant feedback into findings for engineering. The work drew on his ability to make sense of complex problems and help a team move forward on a short timeline.

“As an intern, I was fully on the team,” Garrett said. “We were all working on it together because it was a difficult problem and we had a short timeline.”

The experience showed Garrett that his military background was valuable beyond his knowledge of Army operations. He brought the ability to learn quickly, think critically, work across teams, and create clarity when the problem and path forward were still evolving.

The former battalion commander who introduced Garrett to Onebrief also became his supervisor during the internship. Their regular conversations helped Garrett process what he was learning, evaluate opportunities across the company, and better understand what his transition could look like.

“Having someone who had recently gone through the transition process was incredibly important,” Garrett said. “It provided a lot of clarity about what the internship would be like and what I could expect afterward.”

Recognizing the Tool He Had Needed

Garrett had never used Onebrief before his internship. As he learned the platform, however, he began connecting its capabilities to challenges he had encountered throughout his Army career, including version-control issues, coordination across dispersed teams, and the difficulty of keeping information synchronized while operating under rapidly changing circumstances and timelines. He saw how a shared environment for plans, workflows, and operational data could help military staffs communicate more clearly and reduce risk.

“I’ve personally felt the need for a product like this. As I started to learn Onebrief, I continued to identify ways it could have helped me at every unit I had been in.” — Garrett Ewanouski

Having served as a ground force commander, intelligence team commander, and battalion course of action lead planner, Garrett had experienced military planning from several perspectives. That breadth helped him recognize how Onebrief could support different units and staff sections—and distinguish between a capability that appears promising and one that works in practice.

The internship also gave him the opportunity to evaluate the company behind the product. Across Global Delivery, Product, Design, and Engineering, he saw teams collaborate and share responsibility for improving the product.

“I learned a lot about the high expectations Onebrief has of itself and its product, how the company prioritizes customer needs, and the desire across the organization to build something with real utility for end users,” he said. “That was the most significant part of wanting to join the team.”

That combination—consequential problems, shared responsibility, and a clear commitment to end users—showed Garrett that Onebrief’s mission was matched by how its people worked.

From Intern to Partner Delivery Manager

After completing his internship, Garrett joined Onebrief full time as a Partner Delivery Manager on the Global Delivery team within Customer Relations.

His work includes supporting exercises and customer onboarding while helping improve Onebrief’s learning resources and training curriculum. Together, those responsibilities allow him to help military staffs adopt the platform and continue building their proficiency with it.

For Garrett, the internship did more than introduce him to defense tech. It allowed him to see Onebrief from several perspectives, understand how his military experience could translate, and decide whether the company’s standards, customer focus, and sense of responsibility matched his own.

They did.
