Did you serve out your full term?
I ask because of your phenomenal ignorance of terrain.
The PLA has deployed its armour on the Tibetan plateau, absolutely flat land. The hills of Arunachal Pradesh are sharp spurs, hostile to movement of wheeled vehicles, forget about tracked ones. The PLA mounted at least one major thrust in the east down the Baillie Trail, which followed the river- and valley-bottoms. The moment PLA armour crosses the McMahon Line, it will not be able to move except in handkerchief sized patches. The rest is deep ravines. Trying to motor to Tawang from below, even a heavy motor car barely has a few inches of clearance on the ravine side. And you talk so glibly about tank movement on those trails.
The armour used by the Indian Army during 48 was Stuart tanks, dismantled in Pathankot (I think; I don't remember), airlifted to Srinagar, re-assembled and sent to Zoji La. Do you know what a Stuart looks like?
The Indian Army has an armoured brigade in Ladakh, which has exactly the same terrain as the plateau, not like the sharp hilly spurs of Arunachal.
You are enjoying yourself, aren't you?
....And meanwhile, XXXIII Corps is fast asleep.
Have you noticed, Rangpur is your vulnerability? Do you think you can stand against a push to cut that off? Do you think pushing your armour far forward doesn't expose your flanks? Do you think nobody can read a map other than a silly fanboy sitting and jumping up and down in Britain?
