As I expected Pakistani army has put its experties in use in support of Azeribaijan. That is only explanation why Azeri army is shouting Pakistan Zindabad as well as hoisting Pakistani flags on conquered territories along side Turkish.
Taking into account Pakistani engineered and executed Taliban war against Northern Alliance, TTP, LTTE in Sri Lanka, against Kosovan enemies. I thought Pakistan is behind planning strategising and executing war plans. This Azeri war has full technical support and Pakistani battle strategy. Next step if I am correct will be fighting in mountains. It will start something like this. Azeris will use airforce, drones to dislodge Armenians from high peaks. Put millitary, artillery, on these mountains and gradually descend down something like what Pakistanis did in Swat against TTP. Instead of fighting up mountain ... fight down it. If you see that happening you know Pakistanis are involved.
Based on what I know, Pakistan is using its strategy, designed to take back Kashmir. Its this strategy and they are putting it into practice in various theatres of world. Infantry must have dedicated air wing which they can employ in support of infantary - even UAVs would be amazing.
