Ukrainian army prepares for counteroffensive with revamped drones and artillery.

Ukrainian soldiers have modified commercially-available drones to carry explosives that can destroy Russian tanks and heavy military equipment. The drones are not vulnerable to Russian jamming systems and are airborne for such a short period of time before detonating that radio electronic interference is also ineffective. The Ukrainian Armed Forces are developing quickly in this direction and plan to use drones extensively in their counter-offensive against Russian forces occupying swathes of Ukraine's east and south.
