Yes, indeed, I am aware of Red Army "Deep Battle" and how they combined this with "Maskirovka" to aid in setting up conditions for the numerous penetrations that led to the collapse of the front. Note that T-34s, SU-85s and the early IS tanks were not confined to the roads running without tracks.
Red Army operations were fine tuned between late 42 and mid-44 and the doctrine called for the front to be penetrated in multiple areas such that reserves were soon exhausted/overwhelmed and the tactical and operational depth of the defence was penetrated and could not be repaired. This gave the Germans bad options - retreat, surrender, or die in place.
Bagration's success was also largely due to Makirovka, or Red Army deception tactics. The German command was convinced the summer offensive would be resumed in the Ukraine/southern Poland, believing they had located most of the Red Army mobile forces in the south. As such the reserves for AG Centre were almost non-existent. When Bagration began, the Red Army had some 1.6 million troops, 32,000 artillery pieces and nearly 6000 tanks on the attack front (achieved by thinning other non-active fronts). AG Centre could muster only some 500,000 men about 3000 guns and less than 500 tanks and AG.
Despite a few local defensive successes, the Red Army went through the German front like butter. The initial assault teams were soon followed by larger exploitation forces that widened the breaches and pushed deep into the German rear. Note that the Germans had little/no opportunity to slow these drives as thier main strength was in the south. There was little that one weak panzer (20th) and a de-motorised infantry division (14th) could do.
Combined with follow up offensives in the north Ukraine and southern Poland, the German front from Riga to the Carpathian Mountains had effectively ceased to exist. Similar to what happened in the west, the Red Army offensive out ran its supply and staggered to a halt along the Vistula/East Prussian border and near Riga.
There are numerous texts available, Glantz and House (of course), Citino (very good), Zaloga and Krivosheev are all worth the read.
I would also recommend two monographs by Lt Col. (ret) Richard Armstrong (US Army). Colonel Armstrong was a Red Army analyst and intelligence officer in the US Army. Both papers explore the development of Red Army operational art and the use of deception in creating the conditions for victory.
