The Arunachal Scouts role are similar to that of theSikkim and Ladakh scouts, an infantry regiment of the Indian Army that specialized in mountain warfare tasked to guard Indias borders.
The Ladakh Scouts is an infantry regiment of the Indian Army, nicknamed the "Snow Warriors" or "Snow Tigers". The regiment specialises in mountain warfare, and its primary role is to guard India's borders in the high altitudes of the union territory of Ladakh. China's continued interest in staking a claim in India's northeast has led to China's practice of referring to the Arunachal Pradesh region as 'Southern Tibet' paired with an increased Chinese militant presence at the border led to the formation and mobilisation of the Arunachal Scouts, as a means of reinforcements for the Ladakh and Sikkim Scouts.
