These T-72 tanks have wide metal skins that cover almost the entire turret and hull. And the ends of the 125 millimeter caliber main guns stick out from under the hull, making these armored tanks look like mechanical turtles – hence their nickname: “turtle tanks”.
All the turtle tanks apparently belong to the 5th Motorized Rifle Brigade, a former Ukrainian separatist unit now under Russian command.
Both sides in the wider war are beefing up their tanks with a variety of additional armor designed to block missiles and explosive drones. However, this improvised armor is usually in the form of “cages” or transoms, which do not obstruct the view of the war machine crew, and only slightly restrict the rotation of their gun turrets.
“Turtle” armor, on the other hand, leaves only a small gap in the front for the crew to see through, and likely prevents the turret gun from turning more than a few degrees left and right. The obvious shortcomings of homemade armor make us wonder: what is the 5th Motorized Rifle Brigade really thinking?
Arms historian Matthew Moss has a theory. The turtle tank’s “role seems to be a breakthrough,” he writes.
Demining machine breacher) is a plow-equipped engineering vehicle whose main task is to guide other vehicles through a minefield so that they can approach the enemy line and attack. It is assumed that the enemy will also shoot at the demining vehicle as it destroys the mines, so this specialized vehicle must also be heavily armored.
The US military has the world’s best machine of its kind, a nearly 70-ton machine that’s essentially an M-1 tank without the gun, but with mine clearance equipment attached. At the end of last year, the Americans gave the Ukrainians some of these machines.
The Russian army does not have the same class of demining machines. For the Russians, this function is usually performed by IMR engineering demolition machines, which weigh only about 50 tons and have inferior protection and a clumsy crane.
Faced with Ukraine’s minefields and swarms of tiny drones, and with no dedicated demining machines, the technicians of the 5th Motorized Rifle Brigade may have decided to make their own demining machines, or so Moss suggests.
If this version is correct, the Russians could have taken older T-72 tanks—perhaps ones that already had turret problems—and added two things that every minesweeper needs: additional armor and demining equipment.
Analyst Rob Lee of the Institute for Foreign Policy Studies in Philadelphia noted that the third “Turtle” tank that led the Russian assault on Krasnohorivka last Tuesday was equipped with mine rollers, large wheels that set off mines slightly in front of the vehicle.
This turtle tank was also the first of its kind to have radio jamming equipment aimed at drones — “and after running over a few mines, it kept moving forward,” Lee noted.
The characteristics and actions of the third turtle tank seem to support Mr. Moss’s thesis that the strange improvised machines are home-made demining equipment. If so, they can indeed play this role successfully.
Demining is an incredibly dangerous thing. The Ukrainians have already lost at least two of their six or so minesweepers in intense fighting around Berdych (north of Krasnohorivka). However, so far, only one of the “turtle” tanks has been destroyed – and it was hit by artillery when it was launched after April 8. battle tried to return to their base.
And if there’s any reason to worry about the long-term future of turtle tanks, it’s only because they’re clearly optimized to counter small drones that typically carry no more than a couple of kilograms of explosives.
However, it seems that after the decision of the US Congress in favor of Ukraine, the shortage of ammunition in Ukraine will soon end. And if the Ukrainian minefield-defying turtle-shaped tanks survive well when their biggest threat is small drones, will they survive when the Ukrainians open fire on them with rockets and artillery?
Retired Australian Army General Mick Ryan described the turtle tanks as “one of the really strange adaptations in Ukraine.” But any advantage they give the Russian military “is likely to be temporary,” he added.

Since 2016, the Chinese FAST telescope has located more than 900 pulsating stars
Beijing. Since its launch in 2016, China’s 500-meter aperture spherical radio telescope (FAST) has identified more than 900 new pulsars in space, which, among their uses, function as coordinates for possible interstellar travel , which expands human vision of the cosmos, its operators reported this Wednesday.
Han Jinlin, a scientist at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), quoted by the state news agency Xinhua, indicated that the pulsars detected by the also called Eye of Heaven o Tianyan They included more than 120 binary pulsars, more than 170 millisecond pulsars, and 80 faint and intermittent pulsars, thus expanding the limits of human observation of the universe.
Of the total findings by FAST, 650 were identified by a pulsar snapshot of the galactic plane, according to the report.
Pulsars originate in the core of a massive dying star that are detonated through supernova explosions. One of the important implications of research on so-called fast-spinning neutron stars is to provide cosmic coordinates for possible future interstellar travel, Jinlin said.
He added that in the more than 50 years since the discovery of the first pulsar, less than 3,000 pulsars have been discovered worldwide, and the number of new points discovered by FAST is more than three times the total of those found by telescopes. foreigners during the same period.
A previous report indicated that 224 pulsars were found as of September 30, 2020, and more than 40 high-quality papers were published.
The largest in the world of its kind
The telescope, located in a naturally deep and round karst depression in southwest China’s Guizhou province, has a receiving area equivalent to 30 standard football fields, making it the largest single-dish radio telescope. of the world.
At present, the telescope’s annual observing time is about 5,300 hours, and it plays an important role in the continuous production of scientific research achievements, providing researchers around the world with a powerful tool to discover the mysteries and the evolution of the universe.
Other main scientific fields to be analyzed or detected by FATS include: studying neutral hydrogen, mastering the VLBI network at low frequencies, detecting interstellar molecules and the search for extraterrestrial intelligence.
Observing pulsars is an important task of the Sky Eye, which can be used to confirm the existence of gravitational radiation, gaseous galaxies and black holes, as well as help find answers to many other important questions in physics.
With the new report, the operations of the radio telescope, officially operational since January 2020, have greatly expanded the scope of human exploration of the universe and, in particular, the location of faint pulsars, which are very difficult to detect with other telescopes. positioned around the planet.
In the near future, the telescope will provide the international astronomical community with new perspectives, allowing them to further explore the universe and try to find the unknown, and make greater contributions to helping humans penetrate new fields of cognition, Jiang Peng added. , chief engineer of FAST, quoted by Xinhua.

iPhone SE 4 Leaked Specifications: Design Similar to iPhone 13, AI Camera Features
2024-04-18 02:09:56
The specifications of the iPhone SE 4 have been leaked. The design is similar to the iPhone 13 and comes with a camera that adds AI capabilities.
Now more and more information about the iPhone SE 4 has begun to be released. Recently, Nguyen Phi Hung reported that the camera will come with the feature “AI photography.” Currently, the iPhone already uses Machine Learning to help process it. This may be a reference to this or a rebranding rather than a new feature.
As for the design, the device is more similar to the iPhone 13 than the iPhone 14. The front camera will be a Face ID type embedded in the notch, not a Dynamic Island. The rear camera will be a single camera, similar to the iPhone XR. In addition, the camera does not have a night mode. But it supports cinematic mode shooting at 1080p. Previously, this mode had to be captured by two cameras. At this time, there is no information on how Apple did it.
Let’s take a look at the screen. This time it comes in a size of 6.1 inches. It uses an OLED screen for the first time in a budget model. As for RAM, it will come with 6GB RAM, an increase from the original model that provided 4GB.
The processor chip is A16 Bionic, the same as the iPhone 14 Pro. The price has not been disclosed. It is expected that the iPhone SE 4 will be launched in 2025.
