President Pranab Mukherjee on Saturday said India is committed to peace but will use "all its might" if its sovereignty is threatened.
Speaking at Haismara air base in the eastern sector, the President, who is the supreme commander of the forces, also lauded the India Air Force's role in humanitarian operations.
President Mukherjee earlier presented President's Standard to two IAF squadrons based here. The squadrons which have been honoured are the 18 Squadron and the 22 Squadron.
"Though we remain firmly committed to peace, we will use all our might to protect the sovereignty of our nation. I am confident that our valiant men and women in uniform will rise to the occasion," the president said.
The air base, which is around 15 km away from India-Bhutan border, is considered critical given its proximity to India's border with China, Bangladesh and Bhutan.
Lauding the IAF's role in recent humanitarian operations, Mukherjee said: "The IAF, besides safeguarding the sovereign sites of our nation, has also been at the forefront of all humanitarian aid and disaster relief operations."
