![]() ![]() The viewer has a left and right image and knows how far away the separate images should overlap. They work like binoculars-or even human eyes when a person is good at guessing distances. ![]() Such rangefinders have been around for at least a century. It would be suicide on a battlefield teeming with Ukrainian tanks and fighting vehicles whose crews see through the latest infrared sights.ĭaylight solves the Ural’s spotlight problem, but doesn’t mitigate the tank’s other major fire-control flaw: its optical rangefinder. That a T-72 Ural crew must broadcast its location in order to fight at night basically means it can’t fight at night. With passive night vision, a tank crew can see at night without giving away its presence. The problem with spotlit night vision is that anyone with infrared sights, including the enemy, can see the beam of an infrared spotlight and where it originates. Infrared spotlights became obsolete in the 1970s as passive methods of night vision-infrared and light-amplification-replaced active night vision. The infrared spotlights are how the commander and gunner spot targets at night for their tank’s auto-loaded 125-millimeter main gun. Look for two things: a pair of large infrared spotlights on the right side of the turret and a small aperture for an optical rangefinder, also on the turret’s right. Both are related to the tank’s fire-controls. Its biggest giveaways also are its biggest weaknesses. A Ural isn’t hard to spot if you know what to look for. Three-person, 46-ton T-72 Urals started showing up in Ukraine no later than February, around the first anniversary of Russia’s wider invasion. There might be a thousand old Urals lying around, but it’s possible just a few hundred are intact after five decades of hot-cold, wet-dry cycles. It’s unclear how many Urals Uralvagonzavod produced, how many are in storage and how many of those are recoverable. ![]()
