Tensions between the Indian Army and the Chinese People's Liberation Army (PLA) led to a deadly confrontation between the two sides in the Galwan Valley region of Ladakh on Tuesday.

The border face-off left 20 Indian Army soldiers dead and while Beijing has refused to confirm any deaths on its side, even as an intercept revealed 43 casualties on the Chinese side. Tuesday's encounter between the two South Asian giants marked their biggest military confrontation since 1975. Here's how both countries stack up against each other in terms of military strength and air force prowess:

Manpower and Defense Budget

According to Global Firepower, a website that records military strength and obtains most of its data from the CIA World Factbook, China has more than 2 million active military personnel while India falls short with just 1.4 million active soldiers on its side. However, India has a reserve surplus of 2.1 million soldiers compared to China's 510,000.

China's defense budget of $237 billion is also four times the financial resources reserved for India's military, which is approximately $61 billion.

Despite technological advancements in the modern battlefield, the combat tank still remains one of the primary spearheads for ground offensives. China has as many as 3,500 tanks compared to India's 4,292 tanks.

China may have fewer tanks but dwarfs India when it comes to armored vehicles. The PLA has 30,000 armored vehicles, outnumbering the Indian army's 8,700 vehicles. Similarly, it has more than ten times the rocket projectors at 2,650 versus India's 266.

Moreover, China has 3,800 mobile artillery vehicles as opposed to India's 235 and the field artillery units stand at 3,600 versus 4,060 respectively.

China has a total of 777 naval assets including 2 aircraft carriers, 74 submarines and 36 destroyers while India's fleet strength pales in comparison with 285 assets, with 1 aircraft carrier, 16 submarines and 10 destroyers.
