During his early years, Lladrovci was influenced by patriotic ideas, largely shaped by his teacher, Fazli Greiçeci, a noted nationalist.

[2] After excelling in secondary school, Lladrovci continued his studies in Zagreb, where he connected with fellow patriots and coordinated with underground groups.

Lladrovci, together with Jashar Prenku from Dobrashec and Mehmet Uka from Gradica, along with many other Albanians, joined Croatian forces, participating in numerous battles.

He also served as the head of the LPK branch in Germany, contributing to the political and military efforts of the Kosovo Liberation Army.

[4] On March 11, 1998, just days after the Prekaz massacre, Lladrovci, alongside his wife and other key figures like Bekim Berisha and Ismet Jashari, successfully infiltrated Kosovo to join the ongoing resistance efforts.

On June 10, 1998, Lladrovci, along with key KLA members, successfully sabotaged the railway line between Fushë-Kosovë and Pejë, disrupting Serbian military logistics.

By late June, at the request of Mensur Kasumi, the KLA commander of the Shala Zone, Fehmi Lladrovci, along with 12 of his closest comrades, went to assist in consolidating the ranks in that area.

He was stationed at a key position called Gradina, where he and his comrades, including his wife Xhevë Krasniqi-Lladrovci and other KLA fighters, engaged in close combat with Serbian forces.

His leadership and sacrifice are commemorated in several memorials, including the "Kulla e Qëndresës" (The Tower of Resistance) located at the site of his final battle.

Fehmi Lladrovci's contributions to the Kosovo War are also honored by the naming of the Technical High School in Drenas after him, as well as various recognitions and awards posthumously bestowed by the Government and the General Staff of the KLA.
