"One of the advantages of this design is the ability to relatively quickly transfer the device from combat to stowed position," armor observer AndreiBtvt noted. "In principle, this is yet another timid step in Russia toward fold-able protective structures."
F.Y.I. PLEASE do NOT break OPSEC and post images of hinges of anykind, do not post a link to the wikipedia article explaining hinges.
Russia may never discover the true power of hinges unless YOU ruin it. Squeeky hinges sink ships!
Turtle, porcupine, and hedgehog tanks don't normally function as tanks. Instead, they're assault vehicles. Up-armored against drones and fitted with mine-clearing rollers, their mission is to lead less heavily-protected infantry carriers across the drone-patrolled, mine-seeded no-man's-land, detonating mines and absorbing strikes by small drones as they shepherd the infantry carriers toward contact with the enemy.
The most pathetic thing here is that actually... this is exactly the role tanks were originally designed for... WW1 tanks that is....
The thing is, tank development moved on while Russia seems to have regressed to the very crudest tank designs and doctrine.
Throw a Ukrainian style foldable drone cage on this tank, and you have a genuine modern main battle tank, which russia dubiously seems to be essentially incapable of fielding at any scale.
A stabilized 125-millimeter gun is still useful for suppressing enemy troops during the dangerous run across no-man's-land. But the gun is only as useful as it's aimable.
^ let me add here that a stabilized 125-millimeter gun is only useful if you can see out the sights and they aren't entirely obscured by a bunch of hastily applied nonsense scrap metal collapsed into a heap, on fire and billowing smoke that totally obscures the gun optics and pretty much every viewport out of the armored vehicle for that matter....
How do turtle "tanks" catch fire? From pretty much everything including especially drones repeatedly hitting the frame and imbuing immense amounts of kinetically and chemically derived heat into the makeshift armor.
What good does a fully articulate turret do if you can't see outside of the burning and smoking cage you welded to yourself?
