Intelligence Bureau Assistant Central Intelligence Officers Junior Intelligence
The Intelligence Bureau (IB) is India’s internal intelligence agency and reputedly the world’s oldest intelligence agency. It was recast as the Central Intelligence Bureau in 1947 under the Ministry of Home Affairs. The Bureau comprises employees from law enforcement agencies, mostly from the Indian Police Service (IPS) and the military. In addition to domestic intelligence responsibilities, the IB is particularly tasked with intelligence collection in border areas.
The Class 1 (Gazette) officers carry out coordination and higher-level management of the IB. Subsidiary Intelligence Bureaus (SIBs) are headed by officers of the rank of Joint Director or above, but smaller SIBs are also sometimes headed by Deputy Directors. The SIBs have their units at district headquarters headed by Deputy Central Intelligence Officers (DCIO) or ACIO (Assistant Central Intelligence Officer).
The IB maintains a large number of field units and headquarters (which are under the control of Joint or Deputy Directors). It is through these offices and the intricate process of deputation that a very organic linkage between the state police agencies and the IB is maintained.
In addition to these, at the national level the IB has several units (in some cases SIBs) to keep track of issues like terrorism, counter-intelligence, VIP security, threat assessment and sensitive areas (i.e. Jammu and Kashmir and such). IB officers get monthly special pays and an extra one-month salary every year, as well as better promotions. Apart from the IPS and IAS, IB also recruits from the Indian Revenue Service (IRS).
