Old Footage Of Battle of Debaltseve
Operation began on January 30. A tank attack on the checkpoint that covered the entry into Uglegorsk was successful — after losing 3 vehicles to mines, the DPR tank crews penetrated the enemy defense and entered Uglegorsk proper. To develop this success, the joint assault group on APC, IFV, and trucks deployed through the captured checkpoint into the city, where it engaged the local garrison. The city itself was badly prepared for the defense (there was obvious negligence of the officer who organized the defense of Uglegorsk and of the sector command, which wasn't bothered by this situation). As a result, in less than a day of fighting the enemy was repelled to the south-eastern outskirts of Uglegorsk. Meanwhile, one of the territorial battalions that defended the city ended up in an encirclement. The appearance of a large amount of the NAF forces in the city created a serious operational threat for the whole Debalcevo group.
