At Britain's INTERFLEX training mission for Ukrainian forces, Australian instructors emphasized something that complicates the usual framing of allied military aid: the learning runs in both directions. A substantial share of the practical lessons comes from the Ukrainian troops they are meant to be training, Defence Australia reports.
The Operation Kudu, Canberra's contribution to the UK-led INTERFLEX program, has rebuilt the curriculum around that reality: drone awareness now runs through every module, from urban combat to combat medicine.
"Drones are everywhere"
In the combat area where Ukrainians are fighting, drones are present in every action, shaping battlefield movements, fighting, and survival.
"In their battlespace, drones are everywhere. They affect movement, casualty care, and even how long you can stay in one position," said an Australian Army instructor.
The Australians have built that reality into trench warfare, urban combat, and assault training, and into something more foundational.
Golden hour doesn't always exist anymore
The "golden hour", the foundational rule that severely wounded patients have the best chance of survival if reached and stabilized within sixty minutes, is no longer a reliable assumption on Ukraine's drone-saturated front, the Australian instructors found.
"The golden hour doesn't always exist. Commanders have to plan to hold and support wounded on the position, sometimes for extended periods," one of them said.
Operation Kudu training scenarios now place commanders in situations where they must simultaneously care for casualties, command the unit, and continue the combat mission.
Commanders under constant observation
Decision-making under constant enemy surveillance is now a separate emphasis. Australian instructors are training Ukrainian junior leaders to operate in conditions where any delay or error can have critical consequences because the drone overhead will see it.
"Sometimes mid-course": continuous adaptation
Major Jarrad DeCuyer of the ADF underlined that Operation Kudu's curriculum is in continuous revision: "We assess each course and adjust. If something isn’t relevant to the current fight, we change it, sometimes partway through."
The mutual-learning pattern Australians describe at INTERFLEX is now common across allied training: in February 2026, a NATO war game found that 10 Ukrainians with drones could effectively wipe out two NATO battalions.
