The State Armed Police Forces of India are the police units established for dealing with serious law and order situations requiring a higher level of armed expertise than normal. The State Armed Police Forces exist in addition to the ordinary police services of the various states.
 The various States have different titles for their armed police units. In addition to the general term "Armed Police", other titles in different states include Special Armed Police, Armed Constabulary, Provincial Armed Constabulary and State Military Police. Although the titles are different, their organisation, weapons, equipment and tasks are broadly the same. The central government of India now refers to these forces nationwide as the State Armed Police Forces and discourages use of the term "paramilitary". However, this terminology does not necessarily coincide with the existing terminology of the states of India; For example, the state of Bihar calls its state armed police force "Military Police", which clashes with central government definitions of "military" and "paramilitary". It is not yet clear whether such discrepancies will be resolved.
 The State Armed Police act as a mobile armed reserve activated only on the orders from the Deputy inspector general of police or above. They are not usually in contact with the public except during public events, civil unrest, and natural disasters. They maintain key guard posts and participate in antiterrorist operations. Depending on the type of assignment, they may be or may not be carrying firearms.
 Within states, each police district may maintain its own teams of policemen with higher firearms competence. Such teams, known as "District Armed Police or District Armed Reserve", are for purely local use led by commandant or deputy commandant, functions under the respective district police chiefs.

 The Rajasthan Armed Constabulary is the state armed police wing of Rajasthan Police in Rajasthan. Soon after the independence, the law and order situation along the newly formed 1070 km India-Pakistan border
became a serious problem. Incursions and cattle lifting by Pakistani raiders was a regular feature and it became imperative to put an end to it. In 1949–50, the duty of guarding the border was assigned to the joint forces of the Central Reserve Police Force and the Provincial Armed Constabulary, which continued until 1952.
 In 1952, the Government of Rajasthan decided to raise a temporary special force that could not only be deployed along the border but also assist the civil police in combating the armed banditry known as "dacoity". The first headquarters and training centre was established at Bharatpur in 1952 and five battalions were raised from ex-soldiers, police, and from other sources outside Rajasthan. Each battalion consisted of six mobile companies and one company remained at the battalion headquarters. These battalions were then dispatched to the border areas of Sriganganagar, Raisinghnagar, Barmer, and Jaisalmer. One unit was stationed at Ghat Gate, Jaipur to combat dacoity.
 Within a year of its inception, the RAC proved its worth both on the border and within the State by successfully carrying out its various duties. The members of RAC displayed gallantry and a high sense of morale on occasions that required courage, perseverance, and devotion to duty. Its men battled against all odds, combating not only the enemy but also facing the rigours of the desert areas devoid even of the bare necessities of life.
 The RAC continued as a temporary force until 1958, thereafter it was made permanent. In 1962, two companies were drawn from each unit, and the 6th Battalion was formed. From that year up to the late 1970s, more battalions of RAC were raised as demanded by the situation. India saw two wars with Pakistan and one with China and there was unrest in Jammu and Kashmir, NEFA, as well as Mizoram. RAC battalions were dispatched to these sensitive areas and earned accolades for their courage and efficiency. Later, seven of these RAC battalions were merged into the Indian Border Security Force and two into the Central Reserve Police Force.
 The RAC has formed various specialist units along with its regular battalions.
 In 1998, a Special Task Force, along the lines of the Rapid Action Force of C.R.P.F., was formed to maintain peace in the sensitive districts of Rajasthan. These companies are trained and fully equipped to handle mass riots.
 The training imparted to the select RAC companies is decided as per requirements. There are 3 companies of RAC, which have drawn expert swimmers from various R.A.C. battalions and are being trained for flood relief work.
 There are currently fifteen battalions of RAC including one special battalion formed of only female Constables called the Hadi Rani Mahila Battalion and one further battalion of MBC held as the States para-military force. Out of the 14 regular battalions of RAC, 11 battalions are deployed in Rajasthan while 3 are deployed to Delhi.

 The state of West Bengal has the most extensive armed police organisation and structure in the country. Unlike other states of India, the state of West Bengal has two separate police jurisdictions, that of the West Bengal Police, and that of the Kolkata Police Force. It therefore has two separate state armed police structures, one for each jurisdiction.
 Special forces of West Bengal are:
 The Eastern Frontier Rifles is one of the state armed police force for the West Bengal Police, the other being the West Bengal Armed Police. (i.e. as opposed to the police in Kolkata).
 The Eastern Frontier Rifles were founded as the Frontier Protection Force by the East India Company at some point in the second half of the 18th century, and have had their current title since 1920. The Eastern Frontier Rifles fought in the Second World War, and, as the Bengal Military Police, in the First World War.
 Many contingents of the Eastern Frontier Rifles are kept deployed in various disturbed areas of the state. However, in recent years the force has used for day-to-day law and order duties. Their headquarters is at Salua, near Kharagpur.
 Like the armed police forces of many states, the Eastern Frontier Rifles are currently challenged with the Naxalite insurgency. In February 2010 an Eastern Frontier Rifles camp called Silda was attacked and burnt down by Maoist rebels, resulting in 24 riflemen killed out of a detachment of about fifty. This resulted in condemnation of the state government by the unit's Special Inspector General, Benoy Chakraborty, who claimed his force was "mis-used" and "ill-treated". Morale in the force is believed to be low.
 The Kolkata Armed Police are West Bengal's state armed police force for operations in Kolkata. It is part of the Kolkata Police Force and consists of eight battalions, and three special units. The special units are the Rapid Action Force, the Special Action Force (approx. 160 members) and the Commando Force (approximately 200 members) and also have Combat Force.
