Elements of the 1st Ukrainian Front captured 4 King Tiger tanks near Szydłów, one of them in fully working order, on August 12th, 1944. Near Korozvenki, two more nonfunctional King Tiger tanks were captured.
Preliminary characteristics of the King Tiger are as follows:

According to preliminary information, King Tiger tanks are used as breakthrough tanks by the Germans. For example: during fighting from August 12th to 15th, King Tiger tanks drove ahead of T-6 tanks, and several tanks were on the flanks.
The most prominent weaknesses and methods of combat against this tank are:
- Use all methods applied against Tiger and Panther tanks in combat.
- The weakest parts of the new tank are the gun, turret ring, suspension, rear armour, and turret roof.
- The side armour of the hull and turret can be reliably penetrated by 50-76 mm guns, especially by 57, 85, 122, 152 mm guns, and IS tanks.
Conclusions: based on the main characteristics, it is clear that the King Tiger tank is a modernization of the T-6 "Tiger" tank, with front armour thickened from 100 to 180 mm, which increased the mass from 56 to 68 tons."
