Mathiang Anyoor, also spelled Mathiang Anyur (meaning "Brown caterpillar"), also known as Dot Ke Beny (meaning "Rescue the President"), is a Dinka-affiliated militia group in South Sudan. Originally an "ad-hoc" volunteer force founded in 2012, the militia was transformed into a private army to protect President Salva Kiir Mayardit and army chief Paul Malong Awan. However, the South Sudanese military (SPLA) claims that it is just another battalion. Much of the ethnic violence against non-Dinkas in the South Sudanese Civil War is attributed to the militia.
