Ukraine has been using new mid-range drones to attack key bridges supplying Russia’s rear forces from the south, and battlefield footage appears to show the tactic inflicting significant damage.

The country’s 1st Separate Assault Regiment said it carried out the strikes over the last week on the Armyansk, Henichesk, and Chonhar areas, the three chokepoints between Crimea and the southern front.

Bridges in those areas, situated between 50 and 75 miles from the front lines, have been critical to the Kremlin’s logistics routes to the Zaporizhzhia and Kherson regions.
