Risaldar (often called Ressaidar in the British Indian Army), meaning "the commander of a risala (mounted troop)" in Persian, is a mid-level rank in cavalry and armoured units of the Indian Army. Risaldars generally command squadrons.
The Indian Army has a unique set of ranks, which stand between non-commissioned officers and commissioned officers. During the British Raj, they were known as Viceroy's Commissioned Officers (VCOs), but since the Indian independence movement, they have been called Junior Commissioned Officers (JCOs).
A Risaldar ranks above a Naib Risaldar (called a Jemadar in the British Indian Army) and below a Risaldar Major.
In other arms (such as infantry) the equivalent is a Subedar.
