Much of his career was spent in special forces, Sandhi Yudha RPKAD Group (Kopassus) and later at the Kostrad 17th Airborne Infantry Brigade.

He was the 5th son of 10 brothers from the couple Amin Husin Abdul Mun'im Tanjung and Siti Rawani Hutagalung.

The name of the Seskoad Commander Maj. Gen. Feisal Tanjung began to become a hot discussion after becoming the DKM (Military Honorary Council) for the Santa Cruz massacre in Timor Leste in 1991.

The most tangible results of the DKM recommendations were the removal of General Maj. Gen. Sintong Panjaitan - one of the officers who shined at that time - from the post of Udayana Military Commander.

Everything was removed as a reaction of the government was adopting international demands for the responsibility for riots in Santa Cruz, East Timor which tarnished the image of the Republic of Indonesia at that time.
