Here, we have several concepts jostling for mind-space.
On the one hand, there is the atavistic look-back at what the British called the LRDG - the Long Range Desert Groups, basically Tommies on light four wheel drives looping around the southern flank of both sets of combatants in the desert, and striking unwary and unguarded assets on their right flank. If very lucky, on their left flank as well. That is possible - was possible - in the African desert north of the main Sahara, with its stony soil punctuated by basins of deep sand that swallow up vehicles and soldiers alike - not quicksand, just a smart-alecky way of saying the distances were considerable.
This doesn't work in the Thar. The sand is of a different composition and does not encourage chuntering around looking for trouble. It does encourage camel-based warfare, but somehow I don't see in my mind's eye the XVII Camel Corps giving the enemy any trouble.
It particularly doesn't work, unless someone has screwed up and not patrolled far enough, patrolled long enough, or sorted out the patrol photographs and put them up for photo-interpretation day before yesterday. Day before yesterday in the military lands up with Hannibal, nothing beyond 'now' attracts the normal military attention.
On the second hand, there is that wishful PBI thought that keeps coming up again and again and again, that some big steel monster would turn up to crouch behind, and keep the other guy skipped around with a storm of shell and shot. First, it was the Gatling Gun, without the comfort of cover behind a steel body; then the unmistakable round barrel of the water-cooled Lewis gun, on to the Rolls Royce armoured cars so beloved of the Lawrence of Lawrence of Arabia, until the tank appeared. Then onwards, there was the constant conflict between the fast-moving armoured column, sweeping around obstacles, moving with great speed, assisted on its way by lethal close air support, and the slow, reliable monster that the infantry could walk beside, and could fool itself into thinking that the bulk of steel represented safety.
Again, South Asian armies have to do their homework, if they are to survive to do their classwork. They need to work out what their doctrine will be, in fact, they need to figure out if there will be one all-encompassing doctrine or different ones for different war-conditions, and consequently different inventories of soldiers, weapons and vehicles. Sweeping lunges by armoured formations have never really been tried, and where they were tried in embryo, the numbers were so small that even a comprehensive victory would have given the winning side a possible opening to the other people's jugular.
So the second conflicted concept is the question of how to use armoured vehicles, at high speed to run around the enemy's flanks, or steadily advance guiding groups of foot-weary soldiers.
The third is of protection. Walls of steel normally calm down men who are sheltering behind it, until the opposition finds the weaknesses and outlines them with a few, well-aimed shots. Sadly, even a heavily armoured battle tank cannot offer invulnerability. Consider the amount of protection of armoured vehicles; at their designed level of protecting the occupants against a reasonable chance of heated shrapnel or medium machine guns, that leaves us with an extremely fragile armoured vehicle.
