This was the organization and equipment of the Indian Army rifle section during the 1960s and 1970s.
The Indian rifle section organization very much resembled the British rifle/gun group set up of the time.
The rifle group consisted of the the section commander (Seco) and 6 riflemen (two of which would have had rifle grenade launching attachments). The standard rifle of the time was the 1A1 rifle, which was a license produced variant of the L1A1 SLR, itself an FN FAL variant.
The gun group consisted of the section second-in-command (2IC), a machine gunner and assistant machine gunner. The key difference between the Indians and British (aside from the Indians having 2 more men) was that the Indians maintained the Bren gun (designated 1B) into the 1960s while the Brits adopted the FN MAG, designated L7A2, as the standard section-level machine gun. There were some key exceptions, including the Royal Marines and Paratroopers who retained the L4A4 Bren to supplement the L7A2 due to its lighter weight. The main difference between the 1B and the Bren guns of WWII was a conversion from .303 to 7.62x51mm NATO.
At this time the small unit and rank structures of the Indian Army still resembled those of the British.
