In 1974, Babar was tasked with training and funding Tajiks rebels against Sardar Mohammed Daoud Khan. It was in retaliation of Daoud Khan decade long proxy war against Pakistan and armed incursion by Afghan army in Bajaur in 1960 and 1961. Ahmad Shah Massoud and Gulbuddin Hekmatyar were among the rebels trained by Babar. In 1975, Babar trained rebels staged their first uprising in Panjshir valley. 1975 Panjshir uprising has also been described as the first operation conducted by Inter-Service Intelligence (ISI) in Afghanistan. Before this, ISI did not conduct any operation in Afghanistan. The uprising though unsuccessful, had forced Daoud Khan to change his ways and end his proxy war against Pakistan.
