Yep... Chinese always come in Huge and Rapid, take a look at all their Previous combats in Korea and Vietnam. if we think mirroring chinese number then we're wrong....... stop thinking from defending our land to invading Tibet, now that will give a chill to the chinks... makes them want to take us seriously and continue the talks.
Indian government is obsessed with the global image, especially what the white man will think. Right now, desi babus want to play the victim card like Taiwan and Japan. These clowns don't remember that both these countries are US client states and are defended by their firepower while we are on our own.
Also, Indian Armed Forces are not attuned for offensive warfare. Rumbling through the Thar in tanks and IFVs is very different from Himalayan-altitude mountain warfare. Our terrain access is such that we can fight a brutal defensive war but apparently offensive is not going to be good for us - why? Because unless we have a arty-to-arty + a ready rocket force that can match targeting and bombing PLA positions as well as threaten Chinese cities in the Southwest China, our troops will be entering unknown territory. The last time any Indian military force entered Tibet was over 200 years ago under the Dogra rulers of Kashmir. And let's just say that it did not end well for them.
On the flip side, we have the higher ground and can hold the fort pretty well. Meaning the PLA soy boys will be entering a slaughter-house if they decided to try a mix of human wave + mechanized movement. I won't be too concerned about PLAAF as they cannot carry required payloads to really make a lot of difference. Tibet is a plateau while the border is that of the Himalayas. That means the only way PLA has some advantage is through using rocket artillery. For them, this will be an uphill fight while for our troops, invading them would mean descending with insufficient firepower.
At this point, my only concern would be that PLA could start dirty and just launch hundreds of unguided rockets from deep inside Tibet to soften our position before sending their p*ssy soldiers in since they know that our troops would make it hell for them.
As for the military deficiencies that we have today are due to the delays and corruption between 2003-2013 which can be considered as the lost decade for our forces. They even lacked BPJs, let alone the flurry of defence equipment that came in in the last 7 years.
