More cannon fodder
The Indian approach is flawed. Throwing 100,000 more troops at China's mechanized military is foolish. The Chinese military machine will bomb those 100,000 Indians and move on.
India's fundamental problem is that it has no answer for China's advanced modern weaponry. 100,000 troops do not constitute an asymmetric response. The Indians need to provide the outline of a plan that would give them a fighting chance.
For example, China developed Anti-Ship Ballistic Missiles (i.e. ASBMs) to sink American aircraft carriers. Furthermore, China has tightly integrated its air defenses against fourth-generation fighters. Also, China has thousands of ballistic missiles to destroy Japanese air bases that may host U.S. F-22 fighters. That's called an asymmetric response and a reasonable war plan.
The Indians lack a comprehensive technological and methodical plan to respond to China's overwhelming military power.

After establishing air superiority, it will require only a few days of "Chinese Rolling Thunder" to eliminate 100,000 Indian troops on the ground.
