Ukrainian military ombudsman Olga Reshetilova said in an interview with The New York Times that the widespread use of drones on the front line means Ukrainian Armed Forces soldiers must be trained in advance for long periods inside enclosed spaces.

According to her, Ukrainian troops are already facing conditions in which they have to remain in bunkers for extended periods, unable to go outside even for sanitary needs or to evacuate the wounded. She described this as one of the consequences of the changing nature of combat.

Reshetilova said this situation requires changes to military training doctrine. In her view, soldiers now need to be prepared for prolonged survival in confined spaces, including in temperatures as low as minus 20 degrees Celsius and without the ability to make a fire.

In May, The New York Times reported that new technologies had significantly reshaped modern warfare. The newspaper noted the growing use of precision weapons, layered sensor systems, guided missiles, drones and artificial intelligence-based solutions on the battlefield. Experts cited by the outlet said such technologies are spreading quickly and could influence armed conflicts around the world.

Earlier, former Ukrainian Armed Forces commander-in-chief and current Ukrainian ambassador to the United Kingdom Valery Zaluzhny also said the conflict in Ukraine had changed established ideas about how combat operations are conducted.
