The correct answer is 5.

• The Haryana Armed Police comprises five battalions.
  • Out of Five, three are based at Madhuban near Karnal.
  • Two battalions are based at Ambala and Hisar.
  • On the creation of Haryana State, on 1st November 1966, six battalions of Punjab Police were transferred to this state.
  • These included four Government of India Reserve Battalions which were later merged in Border Security Force/Central Reserve Police Force etc.
  • Subsequently, only two battalions were left and they were stationed at Ambala City and Nilokheri temporarily.
  • 1st Battalion is continuing at Ambala City.
  • The Headquarters of HAP was shifted to Madhuban in the year 1968.
  • The 3rd Battalion of HAP was raised in the year 1969 with its headquarters at Hisar.
  • Thereafter, the 4th Battalion of HAP was raised in 1973 as a technical battalion to maintain essential services like electric supply and road transport during any employee strike.
  • But due to the policy of transfer of HAP personnel to District Police adopted from 1979 onwards, this battalion is now like any other battalion.
