I dont like very much this tank cuz it was a completely deception in WW2, although in the Spanish civil war was much more superior to the german and italian tanks, it wasnt excluded from having mechanical failures. But going back to WW2, in the soviet attack to finland, the t-26 demostrated that it was obsolete against 37mm
cannons or even to anti-tank 20mm rifles whose easily destroyed his thin armour. However, it was a good tank until the late 1930's, which was a good achievement, counting with the new french armoured beasts as the B1 BIS.
