Kosa

Kadart Satyanarayan Reddy (died 22 September 2025), commonly known by his nom de guerre, Kosa , was an Indian militant commander, who was a Central Committee member of the Communist Party of India (Maoist), a banned Maoist militant organisation in India.

Background In 1984, Kosa was married to Radha; soon after their marriage, Kosa decided to have a vasectomy, as the couple consciously concluded that "it was very difficult to have children and fight a guerrilla warfare." Kosa told media that "Maoist cadres did not force their women to undergo sterilisation operation but they themselves opt for tubectomy."

He hailed from Gopalraopally village, now in Rajanna Sircilla district.

In 2009, NDTV stated that Kosa was "one of the top five Maoist leaders in India.

Death Kosa and another Maoist leader, Katta Ramchandra Reddy (alias Vikalp, Raju, Vasu), were killed in an encounter on 22 September 2025 with the security force in Narayanpur district.
