The Ejercito Guerrillero Tupac Katari (EGTK) is a terrorist group appearing in the Covert Ops Essentials expansion of Tom Clancy's Rainbow Six: Rogue Spear. It is formed of indigenous peoples who combine Maoism with racist, anti-white philosophies. Historically a minor threat whose methodology has included attacks on unprotected targets such as power pylons, government offices, and Mormon churches. Their only significant operation to date involved the kidnapping of a businessman, and that was a joint operation with the ELN.

Believed to be limited to extremely rural areas since 1997. May be allied with elements of Chilean insurgent groups such as the FPMR.
