The versatility of the Sikh Light Infantry has seen the regiment conduct operations from conventional warfare on the Siachen Glacier, the highest battlefield in the world, to counter-terrorism. Units of the regiment have also been deployed as part of the United Nations Emergency Force. The regimental motto is "Deg Tegh Fateh", meaning "prosperity in peace and victory in war". The motto has great significance with the tenth Sikh guru, Guru Gobind Singh, with whom the Mazhabi community is very closely associated, Guru Gobind Singh named them mazhabhi as in faithful for their dedication to do good. The regiment's cap badge is a chakram or quoit, with a mounted kirpan. The insignia was designed to honour the Mazhabi community's Akali Nihang ancestry.
