China has infrastructure advantage but not along the whole frontier. Their lines of advance would be predictable. Plus it is not easy operating a 50 ton tank in the Himlayan region. Deploying tanks over roads and railways is one thing, fighting with tanks which will be off-road is a very different matter.
The PLA doesn't need the roads to be along the entire frontier.
A dropping point would be enough for them to engage in a full blown assault.
Plus, you are not factoring in air power. It is true that they need to have weight restrictions due to higher altitude but they have hundreds of fighters to compensate for that as air cover for their light tanks. They're not going to bring their Type 99 main tank here. That's for their eastern plains where they expect a US or Japanese invasion. That is impossible on this side of the border due to terrain.
Not to forget, heli-dropped PLA airborne units (since troop transport is limited again due to carriers). They are a massive quantity.
BTW the Chinese light tank is only 30 tons weight according to various reports and sources.
India already has ATGM mounted BMP-2 which is ligh-weight. Russian tanks are designed to fight in cold weather. Don't forget Russian temperatures drop to -40 degrees.
You are forgetting some key things here:
1- The problem is not the temperature. The problem is altitude.
That is the sole reason why many things that we can do on western border cannot be done here.
2- Terrain. If you do pay a visit to either my state Sikkim or even Arunachal Pradesh, just go to Nathu La here or Bum La in Tawang. That will give you a very, rough estimate on what kind of stuff our soldiers are supposed to face. And these are all well established posts with reasonable terrain and temperature.
A full blown combat will be fought in much more isolated, rough and harsher terrains.
3- The BMP-2s that we have is fine. It is again a numbers problem. We field way too less armoured firepower when it comes to comparing with PLA.
The MKIs can hold the frontier for long, but not all MKIs will be thrown into the combat mix. Because we know that IF such a conflict occurs, Pakistan will attempt a misadventure on the Western front and also utilize elements in Bangladesh, for a multi-front assault. Though Bangladesh would remain neutral in real life (much different from the ones here on PDF), they won't be strong enough to oppose Pakistan using rogue elements in their country.
And with our NO FIRST USE policy, we cannot even threaten a nuclear strike in response to a multi-pronged aggression. Unless of course we break the convention.
We need the following things on the eastern border:
1- Blankets of SAMs. (At least 10 batteries per sector in each state)
2- Blankets of MBRLs and howitzers. (At least 20 batteries of them across the two states)
3- Drones to keep a vigil between the mountain ranges. (At least a dozen of them flying just to monitor the borders.
4- ATGMs to the boot. (in thousands; remember a missile is not as potent in navigating the narrow ridges of the Himalayas as it is on other terrain).
5- ASAP deployment capabilities of Sikkim Scouts or other units of the Army to the frontiers through a strong armoured troop transport system, which has excellent roads.
And this is keeping in mind the worst possible scenario.
Buddy,giving full respect to your views and experience,I would still say that the T 72CIAs are a good bait against the PLA light tanks in that region.I have been to your state multiple times,that's why I know there a quite large number of BMP 2s and T 72CIAs dispersed at different garrisons,I hope you see them every day.
Sure thing. But are they enough? Can they hold a prolonged combat against the lighter, faster and more agile 30 ton tanks that PLA deploys? And how much of that is present?
Remember that while T-72 has been designed for +- 50 degrees, it is not designed for such high altitudes. There will be a certain degree of load penalty. They are not designed to take on the Himalayas. In fact, that is one such reason why US campaign in north Afghanistan and Spetsnaz campaign in the same area in Afghan war, both, failed miserably.
Technology is no match to the nature's fury here.
And I know what you are talking about.Yes,the terrain in some places is traverse-able by tracked vehicles,but there are also steep ridges flanking them,which can be exploited by ATGM teams.Believe it or not,while fighting in the mountainous/urban regions,the man portable ATGMs and LAWs become the biggest threat to any mbt since their lightly armored rooftops,sides and rears become exceedingly exposed to out flanking moves by infantry.So,in my view,sinking a lot of resources into light tanks,would be a bad idea,especially against a foe like the Chinese.
We don't have enough modern ATGMs. Remember a lot of them are also deployed to counter heavy armour from Pakistan.
While Pakistan doesn't have the money to go for a war, the Army cannot just throw back all their cautions.
When we talk about a war, we are talking about a two-front war for granted.
It is better to overestimate the enemy than underestimate them.
The Indian Army has done what was ought to do.They have placed T 72s and BMPs as a blocking forces against potential thrusts by Chinese light armor and as it has been proven many a times in previous wars,whenever a lightly armored vehicle has come face to face against a heavily armored opponent,the former has had their @rses handed to them unanimously.So T 72CIAs,though admittedly old,are still quit good a bait against the type of light tanks that has been deployed by the Chinese in that region.
I hope you're right. We have never used heavy tanks in the Himalayas. That is what I am apprehensive about.
Also since we cannot match the numbers that PLA has, we will need a quality nexus of missiles, MBRLs, SAMs, ATGMs, tanks and MKIs to give a befitting response.
