Afghan Civil War (1989–1992)
The Jamiat-e Islami group was led by Burhanuddin Rabbani, but the main military commander was Ahmad Shah Massoud. This group was also a strong mujahideen group and played an important role in the ultimate mujahideen victory over Najibullah in 1992. They received little to no support from the United States, which meant they had less resources (like money and military equipment) than the Hezb-e Islami group. However, their success was mainly thanks to Massoud's advanced fighting skills.
