Almost six months after the security breach in Parliament House in New Delhi on December 13, last year on the anniversary of 2001 Parliament terror attack, more than 3,300 Central Industrial Security Force (CISF) personnel will take over the complete security duties of counterterrorism and anti-sabotage at the complex from May 20. The CISF staff has been posted after the withdrawal of 1,400 Central Reserve Police Force (CRPF) that are already deployed at the most prestigious symbol of democracy. According to the sources, the CISF personnel at the Parliament will be deployed at after a refresher training in baggage screening, personal frisking, bomb detection and disposal, swift action of terrorist counter, sniper tasks etc. They have also been trained on Black Cat commandos of National Security Guard (NSG). All about CISF and CRPFThe Central Industrial Security Force (CISF) and the Central Reserve Police Force (CRPF) are both prominent paramilitary forces in India, but they have distinct roles, functions, and operational areas:Role and Mandate:CISF: Primarily responsible for providing security to various critical infrastructure installations, including airports, seaports, nuclear power plants, space establishments, government buildings, and industrial units.CRPF: Primarily tasked with maintaining law and order, counter-insurgency operations, and dealing with internal security threats such as terrorism, insurgency, and left-wing extremism. They are often deployed in conflict areas and troubled regions to assist local law enforcement agencies and maintain peace.Functional Areas:CISF: Focuses more on industrial security and protection of vital installations, along with providing security consultancy services.CRPF: Engages in a wider range of operations, including maintaining public order, counter-terrorism, riot control, and assisting in elections and disaster management.Training and Recruitment:CISF: Specializes in training for industrial security, bomb detection, and disposal, as well as disaster response.CRPF: Provides training for counter-insurgency operations, jungle warfare, riot control, and other aspects of internal security.Deployment:CISF: Primarily deployed at industrial and commercial establishments, airports, government buildings, and other critical infrastructure locations.CRPF: Deployed in conflict areas, troubled regions affected by insurgency or terrorism, and during elections or major events requiring security reinforcement.Authority and Jurisdiction:CISF: Operates under the Ministry of Home Affairs (MHA) and its jurisdiction is primarily over the security of industrial and critical infrastructure assets.CRPF: Also operates under the MHA but is deployed across the country for various law enforcement and internal security duties, including dealing with insurgency and maintaining public order.In summary, while both CISF and CRPF are paramilitary forces under the Ministry of Home Affairs in India, they have different roles, functions, and areas of operation. CISF focuses on industrial security and protection of critical infrastructure, while CRPF is more involved in maintaining internal security, counter-insurgency operations, and assisting in law enforcement activities across the country.Reason for change in deploymentFrom the Central Reserve Police Force (CRPF) to the Central Industrial Security Force (CISF) for security at the Parliament House in India, could be due to several reasons, though without specific context, its challenging to pinpoint the exact cause. However, there are some general reasons why such a change might occur:Expertise and Training: The CISF specializes in industrial security and has extensive experience in securing critical infrastructure, including airports, government buildings, and industrial establishments. If theres a perceived need for a specialized force with expertise in securing high-profile government installations like the Parliament House, the CISF might be considered more suitable for the task than the CRPF.Security Assessment and Recommendations: Changes in security arrangements are often prompted by security assessments and recommendations made by security agencies and experts. If a comprehensive security review suggests that the Parliament House requires a different approach or a higher level of expertise, switching to the CISF could be part of the recommended changes.Policy or Administrative Changes: Sometimes, changes in security arrangements are driven by broader policy or administrative decisions within the government. These decisions could be influenced by factors such as perceived threats, changes in security protocols, or organizational restructuring.
