Ukraine has gone from accepting just about any old weapon to showing Western militaries how modern war is fought

Ukraine's allies now see it as a key partner that helps their own future security.Serhii Mykhalchuk/Global Images Ukraine via Getty ImagesUkraine started its fight against Russia's full-scale invasion accepting any help it could get.Some of that equipment was decades old and pulled from storage.Now, allies are studying Ukraine's technology and battlefield tactics.Ukraine has gone from taking almost any military support its Western partners could spare to helping those countries prepare for a new kind of warfare.At the beginning of Russia's full-scale invasion, Ukraine was fighting for its survival with hand-me-downs from partner nations, not cutting-edge weaponry. Now, Ukraine is developing weaponry, production methods, and tactics that Western militaries are studying as they prepare for the possibility of another large-scale war.When the invasion came in 2022, Ukraine was "asking for anything," Davyd Aloian, the deputy secretary of the National Security and Defense Council of Ukraine, told Business Insider. "Any support was fine for us. Even if it was 80-year-old armored vehicles, we were thankful for that because we didn't have anything."He said Ukraine's approach began to change in 2023. Ukraine had "to be more smart and strategic, and we started to work very actively in our own defense industry," he said, taking a larger role in its own weaponry supply chain. It focused initially on conventional weapons such as artillery and armored personnel carriers, but then began shifting toward new innovations in drone warfare, from drone vessels to flying attack drones.In 2024, the country dramatically accelerated its development of drones and other systems to offset its disadvantage in population and military size. It's companies began making drones and components on a new scale, and Ukraine's use of drones exploded beyond anything that partners had previously experienced.Then in 2025, Ukraine started making ground robots in larger volumes to carry supplies, evacuate casualties, and perform other dangerous battlefield tasks. The country also further expanded its drone production. Aloian called it "the year of scaling of those defense technologies."Allies want to learn from Ukraine's battlefield technology and how it is able to develop and make it so quickly.Viktor Fridshon/Global Images Ukraine via Getty ImagesNow, in 2026, he said, the new focus is on "the implementation of more complicated software solutions, with AI and so on."He said this year has "really showed us and our partners that we transformed from this country that asked for anything to the country that's not just capable but ready to give those lessons that we have learned and to contribute to the common defense."Ukraine has transformedIn 2022, Ukraine accepted weapons that allies had retired or held in storage, some of which required refurbishment. They included 1960s-era German Gepard self-propelled anti-aircraft guns that Germany retired in 2010 and Soviet-designed Su-25 aircraft from North Macedonia that had not flown since 2003.Allies gradually agreed to provide Ukraine with advanced Western weapons it had long requested, including modern tanks and F-16 fighter jets; however, those decisions often came only after lengthy debates over escalation, readiness, and limited stockpiles.Unable to wait, Ukraine invested heavily in its own defense industry, developing new battlefield technology and adapting production and tactics to the new demands of modern war at a pace Western officials say their own institutions struggle to match.That experience, though trying, has made Ukraine an increasingly important partner for Western militaries trying to understand a rapidly changing battlefield. Ukraine's circumstances are distinct, and lessons developed during this existential war against Russia may not transfer directly to every NATO force or conflict; however, the alliance isn't overlooking this opportunity to sharpen its skills.Ukraine is still accepting old gear. It is a hugely attritional war that chews through weapons so quickly that quantity can matter as much as sophistication. Older systems have also remained useful when adapted to current threats.Ukraine has used MIM-23 HAWK air defenses, retired by the US more than two decades ago, to shoot down Russian attack drones and missiles. A Ukrainian unit said this week that it shot down two new Russian missiles with Swedish 40-mm Bofors L70 anti-aircraft guns that are more than 70 years old.Older Western weapons like the MIM-23 HAWK have been powerful for Ukraine.Nina Liashonok/Ukrinform/NurPhoto via Getty ImagesBut Ukraine is also rapidly developing systems such as ground robots and interceptor drones designed to destroy incoming drones. Allies want access to some of that technology and want their defense industries to learn from Ukraine's development and production methods.NATO Secretary General Mark Rutte said last year that "Ukraine is a powerhouse when it comes to military innovation and anti-drone t
