Moreover, experiences on the Eastern Front by both German and Soviet towed anti-tank guns reinforce the importance of battlefield geography. The successful "Pakfront" tactic was developed by the Germans and was copied by Soviet forces. Pakfront was similar in nature to US towed tank destroyer strategy, whereby large numbers of towed anti-tank cannons were placed in an area that enemy armor was expected to go through. What made Pakfront unique was that these hidden cannons would then co-ordinate their fire upon a single armored vehicle (usually command tanks) with the intention of causing a catastrophic kill. Pakfront was successfully used by the Soviets during the Battle of Kursk. It is important to note that the fighting terrain on the Eastern front was often fought on the flat expanses of the steppe, which, like North Africa, allowed units to engage at maximum range.
