Serving as an early fighter, coordinator of military operations, and a crucial link between the regions of Drenica, Dukagjin and Pashtrik during the initial phase of resistance against Serbian forces, he is regarded as a prominent leader and also a close comrade of Adem Jashari.

During his youth, Krasniqi witnessed significant political unrest in Kosovo, particularly the 1981 protests, which shaped his early sense of injustice and resistance against Yugoslav oppression.

On October 10, 1996, Mujë Krasniqi and his cousin were forced to flee from their homes and sought refuge with the Jashari family, while hiding together from the Serbian regime.

Three weeks after that, on November 28, 1997, during the funeral of the teacher Halit Geci in Llaushë, Rexhep Selimi, along with Mujë Krasniqi and Daut Haradinaj, made the first public appearance of the Kosovo Liberation Army (KLA).

[4] Between November 1997 and June 1998, Krasniqi operated in the Drenica and Dukagjin areas, playing a crucial role in securing illegal arms corridors and expanding the ranks of the KLA.

He was instrumental in forming the elite combat unit "ALFA" of the KLA, which included prominent fighters such as Bekim Berisha, Besim Mala or Rasim Kiçina.

However, on September 27, 1998, the Serbian forces demonstrated their brutality by massacring 26 members of the Deliu family in Abri, showing their frustration, at not being able to break the KLA's resistance.

[8] On December 14, 1998, while leading a contingent of 143 KLA fighters transporting arms and ammunition from Albania to Kosovo through the Pashtrik Mountains, Krasniqi's unit was ambushed by Serbian forces near the Gorozhup area.

[8] In honor of Mujë Krasniqi's life, several recognitions have been awarded by the General Staff of the KLA, the Ministry of Defense of the Provisional Government of Kosovo, the Municipal Assembly of Klinë, and other institutions.

Alongside his comrade Beqë Sefë Gashi and his cousin Rexhep Selimi, he composed and performed songs that became symbolic anthems for the KLA ( like Kreshtat e Kosovës).
