You didn't get my gist.
While you veered off towards the region/terrain, you didn't notice that I mentioned operating an Armored Division with a Mechanised Division under a Corps HQ, whether its the 31st or 5th Corps. Such a combination could lead towards forming another Strike Corps or Armored/Mechanized Corps, one that doesn't already exist in PA unless the Infantry Divisions of Strike Corps are fully mechanised just like the Mechanized Divisions of PA. This could mean 8-12 Armored Regiments, 8+ Mechanized Infantry Battalions, 2-4 Anti Tank Regiments, 6-8 Artillery Regiments, 6 AD regiments in that formation and I haven't factored in the Infantry Division as yet.
That's 360 - 540 x VT-4 MBTs charging at the enemy under a single Command.
If such a formation comes up, it would raise alarms in IA HQs. Strategies, tactics and operations will be reviewed and renewed by both sides. New Exs will have to be conducted. This raises the important aspect:
Does PA command have the capability to manoeuvre Armored and Mechanized divisional sized formations under a Corps HQ together in a war with India?
