The rockets appear to be being used in an adapted M261 rocket pod on the wing of a Mi-24V. US-made hardware is gradually replacing the Soviet-era weaponry that Ukraine has long used. A few months after the US government announced the supply of Hydra 70 mm rockets to Ukraine, we now have evidence of them being used on Mi-24 Hind helicopters.
