Relax! Your optimism is a little misplaced!
Paradoxically, while the tank itself has demonstrated high speed, firepower, and mobility, at 67 T, the tank is too heavy to be deployed across the border with Pakistan. It is unable to effectively traverse terrain filled with natural and/or artificial obstacles. Or areas criss-crossed with rivers and canals. That rules out most places in Rajasthan, Punjab and the mountainous terrain of the J&K sector.
This has forced the army to identify areas where the Arjun-II can safely be deployed and its operational units based. This probably means the Arjun-II will not fight alongside the T-90s and T-72s. It will certainly not be part of the Indian Armys strike corps formations, as it could get bogged down in unfamiliar terrain. This runs counter to the philosophy of armoured formations, which are designed for mobile offensive operations deep inside enemy territory.
Unlike the T series tanks that have been airlifted to high altitudes like Leh and even out of the country, the Arjun cannot be airlifted by the IL-76 and C-130 J transports of the Indian Air Force (IAF). The C-17 Globemaster inducted by the Indian Air Force (IAF) has a maximum payload of 75 tonnes insufficient to airlift the 67 tonne Arjun Mk-2 with attendant support equipment.
In a nutshell, they would most likely be used only in holding formations to be used against the enemy's strike corps, defeating the very basic concept of the requirement of tactical and strategic mobility of armored formations.
Sorry to burst your bubble, but then I thought I need to put this out so people don't start celebrating prematurely!
