Du scheinst recht zu haben:
The photo confirms what some observers grimly predicted: the Kremlin is shipping T-55s to Ukraine without upgrading them. The tank in the photo has the same active infrared optics the T-55 had in the late 1950s.
And there’s no evidence the Russians have added blocks of explosive reactive armor in order to reinforce the T-55’s original—and thin—steel armor.
In other words, the T-55s really are 1950s technology. And hopelessly obsolete compared to even the oldest tank in the Ukrainian inventory.
