Security guard

A security guard, security officer, or protective agent is a private person who is paid to protect property and its assets (people, money, etc) by utilizing preventative measures. They do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, observing (either directly, through patrols, or by watching alarm systems or video cameras) for signs of crime, fire or disorder; then taking action to minimize damage (example: warning and escorting trespassers off property) and reporting any incidents to their client and emergency services as appropriate. Their international (at least in the United States of America and Canada) symbol of brotherhood is The Thin Green Line. Security officers are generally uniformed to represent their lawful authority on private property.

Until the 1980s, the term watchman was more commonly applied to this function, a usage dating back to at least the Middle Ages in Europe where there was no form of law enforcement (other than it being a private matter). This term was carried over to North America where it was interchangeable with night-watchman until both terms were replaced with the modern security-based titles. Security guards are sometimes regarded as fulfilling a private policing function.

National security

National security is a concept that a government, along with its parliaments, should protect the state and its citizens against all kind of "national" crises through a variety of power projections, such as political power, diplomacy, economic power, military might, and so on.

The concept developed mostly in the United States after World War II. Initially focusing on military might, it now encompasses a broad range of facets, all of which impinge on the non-military or economic security of the nation and the values espoused by the national society. Accordingly, in order to possess national security, a nation needs to possess economic security, energy security, environmental security, etc. Security threats involve not only conventional foes such as other nation-states but also non-state actors such as violent non-state actors, narcotic cartels, multinational corporations and non-governmental organisations; some authorities include natural disasters and events causing severe environmental damage in this category.

National Security Guard

The National Security Guard (NSG) is a special forces unit under the Ministry of Home Affairs (MHA). It was raised in 1984, following Operation Blue Star and the assassination of Indira Gandhi, "for combating terrorist activities with a view to protect States against internal disturbances".

NSG is under the authority of Ministry of Home Affairs (India), However it is not categorised under the uniform nomenclature of Central Armed Police Forces. It has a special forces mandate, and its core operational capability is provided by the Special Action Group (SAG) which is drawn from the Indian Army. The Special Rangers Group (SRG), the police component of NSG, which also handles VIP security, is composed of personnel on deputation from other Central Armed Police Forces and State Police Forces.

The NSG personnel are often referred to in the media as Black Cats because of the black dress and black cat insignia worn on their uniform.

Mission

The National Security Guard (NSG) was set up in 1984 as a Federal Contingency Deployment Force to tackle all facets of terrorism in the country. As a specialized counter terrorism force, it is intended for use "only in exceptional situations" and not meant to take over the "functions of the State Police Forces or other Para Military Forces". Yet, over the years its role has vastly expanded to provide personal security to influential politicians quite independent of the real threat that they face. Many politicians seek personal security details for themselves and their family for reasons of ego, prestige, and power projection.

Special forces

Special forces and special operations forces are military units trained to perform unconventional missions. Special forces, as they would now be recognised, emerged in the early 20th century, with a significant growth in the field during the Second World War.

Depending on the country, special forces may perform some of the following functions: airborne operations, counter-insurgency, "counter-terrorism", covert ops, direct action, hostage rescue, high-value targets/manhunting, intelligence operations, mobility operations, and unconventional warfare. The term “special forces” in the US refers to the US Army's forces while the term “special operation forces” refers to all units. In Russian-speaking countries special forces are typically called spetsnaz, an acronym for "special purpose". Likewise Russian speakers refer to special forces of other nations as spetsnaz, for example US Special Forces would be referred to as Amerikanski spetsnaz in Russian.
