I believe Pakistan use A-100 300mm MRLS for countery-battery role in Corps. Long range of 52 calibr wheeled SPG for strike formation in Corps. 45 tracked calibr SPG for strike formation in Armored or Mechanized division. So lack 122mm tracked calibr in division for countery-battery role.In future here I think wheeled SPHs might be used more for counter-battery role leaving tracked for strike formations.
Any idea about whether do we have SADARM type shells/rockets for counter battery/anti armor role?
Leaving 12 guns for training PA can raise 16 to 24 regiments of wheeled SPHs (depending upon using 18 or 12 guns per regt).
These can be then divided within the 7 india facing corps level formations for Corps Arty Bdes (as partial/full replacement of towed artillery in these brigades).
