>Where have the tanks and arty been ordered yet?
Arty is pending, this is true, though I have a sneaking suspicion this is because of the stellar performance of the Bofors and other howitzers in recent conflicts, which led the army to believe there is no rushing need to replace.
As regards the tanks, the IA Armoured Corps fleet has gotten MASSIVE upgrades. Tonbo Imaging is outfitting BMP-2s with see through armour systems, new IR/Night sights and other firms/PSUs are getting the BMP-2s other new systems, including new shells. The 2A46M gun on Indian T-72s has received new shells to replace the old 3BM42s and the 2A46M-5 gun on our T-90s is getting absolutely stellar rounds capable of over 700mm at 2km. Our T-72s have been upgraded in the hundreds and the T-90s are replacing T-72s in multiple regiments, with more on the way. The T-72s are entering storage where they can be used whenever necessary.
>Troops along the LAC
Very, very few still have the M1979 helmets. INSAS is also being replaced and multiple AK variants are making their way from Kashmir to the LAC. In Kashmir, the INSAS has long since been "retired" (unofficially) by AKs and variants thereof. Furthermore, the Indian troops on the LAC are getting much better personal equipment (like PCs) but the altitude and lack of oxygen make carrying such a load nearly impossible, especially when you have to start throwing punches
