Analysis of information sources in references of the Wikipedia article "Sikh Regiment" in English language version.
Some regiments, such as the Sikh Regiment and Sikh Light Infantry, are "single class," and therefore recruit combat troops only from members of a specified class, such as Jat Sikhs and Mazhabi and Ramdasia Sikhs.
For example, all the Sikh units in the Indian Army do not come from the same mother regiment. There are two regiments, the Sikh Infantry Regiment (composed of high caste Jat Sikhs) and the Sikh Light Infantry Regiment (composed of lower caste Mazbhi Sikhs).
Moreover, with the exception of Gurkhas (recruited in Nepal), Sikhs remain the only community to have infantry regiments drawn exclusively from their own numbers: the Sikh Regiment (manned, though not officered, by high-caste Jat Sikhs) and the Sikh Light Infantry (manned entirely by Mazhabi, or Scheduled Caste, "untouchable" Sikhs.
