This is good analysis. The General highlights importance of artillery which is quite right. I would like to use artillery on concentrated Chinese forces. But, I would want armour and infantry to roll through whole Tibet and reach Chinese mainland.
Chinese with a lot of stress on firepower probably wouldn't be so effective in Himalayas. Even though we used a lot of artillery in Kargil, it took infantry to dislodge the infiltrators. Lots of firepower without infantry in Himalayas might not be effective.
