 Incidentally, special Soviet units would have also performed secret attacks on Iranian territory to destroy suspected mujahideen bases, and their helicopters then got engaged in shootings with Iranian jets.Conversely, some regions such as Nuristan, in the northeast, and Hazarajat, in the central mountains of Afghanistan, were virtually untouched by the fighting, and lived in almost complete independence.Periodically the Soviet Army undertook multi-divisional offensives into mujahideen-controlled areas.
