Important Points:

  • DRDO = Established in 1958, responsible for research and development of defence technologies.
  • BSF = Founded in 1965, guards India's land borders and prevents trans-border crimes.
  • CRPF = Raised in 1939, it is the largest paramilitary force maintaining internal security.
  • NSG = Established in 1984, specializes in counter-terrorism and hostage rescue operations.
