The proposal to raise the Arunachal Scouts along the lines of the illustrious Ladakh Scouts for defending the border with China was proposed by former Indian Army chief and Governor of Arunachal Pradesh, General J. J. Singh, in 2008. The proposal was approved by the Union Cabinet in 2009. The new battalion was carved out of the Assam Regiment. The first battalion was raised in 2010, and the second in 2012. On 1 May 2012, the 1st Battalion was given the primary responsibility for providing security for Arunachal Pradesh's border with China, supported by other regiments located farther from the border and the Indo-Tibetan Border Police.
