PIF meaning in Military and Defence ?

The Punjab Irregular Force (PIF) was created in 1851 to protect the NW frontier of British India. It was termed "Irregular" because it was outside the control of the Regular British East India Company Presidency armies of the three Presidencies of Bengal, Bombay or Madras, but was under the control of the British chief magistrate of Punjab, known as the President of the Board of Administration from 1849, then as the Chief Commissioner from 1853. Its soldiers were not subject to parade ground drill and showed unconcern towards routine orders given to regiments of the line. They practiced swift tactical movements in small groups, showing special elan and flair. It comprised the various regiments raised earlier for the same purpose on the orders of General Charles James Napier and Col. Sir Henry Montgomery Lawrence between 1843 and 1849 of the former Frontier Brigade established in 1846 and Transfrontier Brigade established in 1849. In 1865, the PIF was redesignated Punjab Frontier Force and in 1903 became the Frontier Force. In 1922 it was split into 2 separate units: the 12th Frontier Force Regiment and the 13th Frontier Force Rifles. In 1947, both were ceded to the new state of Pakistan, which in 1957 amalgamated them, together with a 3rd unit, the Pathan Regiment which Pakistan had earlier created from elements of both, to form the Frontier Force Regiment. Within the latter regiment, the first 15 of its 52 battalions can trace their origins back to original British Army regiments, and the regiment still maintains the lineage of its predecessor British regiments. Members of the PIF traditionally referred to themselves with pride as "Piffers", a tradition very much maintained within the Pakistan Army.
