To put this debate into perspective, the following three imperatives should be considered.
One, modern warfare, which is driven by technology, has transformed in two ways. Instead of linear battlefields (either air-land or air-sea), there are now six battlefields whose optimisation would determine the war outcome. These are land, air, sea, space, cyber and electronic. Given these disparate battlefields, the Chinese focus has shifted to non-contact war with limited or no loss of lives to own troops. China would use its stand-off, precision weapons including cruise missile, laser bombs, armed unmanned aerial vehicles and so on for destruction, rather than fight soldier-to-soldier with the Indian army. Given this situation, in India, the air force and not the army would lead the land war. This is not acceptable to the army chief, General Bipin Rawat who recently said that the army should lead the land war. Thus, either the modern war is not understood by the army or there is a dogged attempt to resist drastic downsizing of its bloated numbers.
