Around 30,000 troops of Indian Army are in direct confrontation with Chinese troops along the Line of Actual Control (LoC) in Ladakh.
India deployed additional three brigades since the violent face-off last month in which at 20 Indian troops were killed.
In normal times six brigades that is two divisions are maintained along the LAC in Ladakh, even as troops are deployed in and out on a rotation basis.
However, after the June 15 violent clash, the Army called for three additional brigades (each brigade constitutes around 3,000 troops and support elements).
Around 10,000 troops for the three additional brigades were brought from Punjab, Himachal Pradesh and Uttar Pradesh, report said.
In all there are three Army divisions along the LAC under the XIV Corps Command, as of today.
Reports said some para special forces which played a key role in the 2017 surgical strikes against Pakistan, have also been sent to Ladakh.
The Indian para troopers come from over a dozen special forces regiments who are trained in high-risk operations in extremely difficult terrain. Similarly, five battalions of Ladakh scouts, an infantry regiment of the Army, is operational for support in the mountain warfare.
Since the violent clash in the Galwan valley, the Indian Army reinforcements have been backed by its M-777 ultra-light howitzers bought from the US, sources said. The American howitzers, sling-loaded to helicopters, are known for their precision artillery fire up to a range of 24-30 kms in mountainous regions.
Air Force’s transport aircraft, that is C-17 Globemaster III, sources said, have been used to airlift soldiers, infantry combat vehicles and heavy tanks like T-72/T-90 tanks.
According to military sources, the Army has also pressed into service, the Russian Sukhoi-30 fighters, MiG-29 jets, Ilyushin-76 heavy-lift planes, An-32 transport planes, Mi-17 utility helicopters, and BMP-2/2K infantry combat vehicles.
