Sikhs do NOT form a massive bloc; only the Punjab Regiment, the Sikh Regiment and the Sikh Light Infantry are exclusively Sikh; these are far outnumbered by non-Sikh formations, although Sikhs are to be found in every arm, in every specialisation, including the Navy and the Air Force. Perhaps they seem to be present in disproportionate numbers by being so distinctive and recognisable.
Sometimes people also get misled by the higher proportion of Sikhs in the officer cadres. This should not lead to an erroneous extension to the OR. The percentage of officers within the Army is itself miniscule.
LOL.Came across this heartening moment of our army:
The CO of the Unit is a Bengali Officer who is sporting a Pagri and beard and carrying the Gurugranth Sahib on his head.
