There are few ideas that I might have
A) ARMY.
1. It is better to go for Tracked AFV armed with say 30mm or 35 mm gun (with ability to attack low flying planes and helicopters also) and armed with ATGMs. This is a more effective tank killer than another tank and from a distance,
2. Invest in something like quadruple drone that has sensors and ability to lift / carry a modular pack carrying either 4 ATGMS or 75 mm fast firing gun with 20 round magazine. This is will be in a way useful like pop up, fire at the targets, pop down and scoot.
3. Develop Army Air force that will handle the role of CAS and operational strike. IAF would carry out strategic, and tactical roles, and also have role to overlap the role of AAF.
4. Give them more tactical attack drones that can fly high and provide support and intelligence to army units.
5. Induct the indigenous ATAGS
6. Also if possible to develop a 155 mm gun with say 10-15 round magazine this might help to have a very high rate of fire required to supress the enemy and few guns can do a lot than more guns due to high rate of fire.
B) NAVY.
1. Invest in big Hovercraftsto be used as force projection vessels..
2. Invest in naval reconaissance and develop an AEW system based on US-2 Amphibious plane
3.Have Ground based naval aviation that co-ordinates with the naval ships and ensures secure maritime birder. Use planes like Tejas to provide CAP for important naval bases but used and flown by Naval pilots.
4. Invest more in nuclear submarines than an aircraft carrier., ACs are tremendous sight but also the most tempting target. Submarines are not that easy targets if they are stealthy.
C) IAF
1. Order more Tejas and build up nos, Retire any IAF officer who is not in favour of inducting tejas or bypass them for promotion.
2. Go for a squadron of PAKFA, fly them and know them and suggest changes for FGFA (PAKFA MKI)
3. Give the inputs to AMCA project and develop AMCA involving the user. I prefer AMCA to be primarily a Nava plane as if with many Naval air base, they would have a requirement of about 200 planes in total.
4. Go for more S-400 units and put most of them near India china border to nullify the threat of PLAAF.
This is some of the steps that I might go for
@mendosa Well to a point i agree with you we don't actually need more numbers of fighters ..Because we can only cover the entire range of pakistan with the current generation fighters from our bases ..China none of our fighters for that sake any fighters available in the world today has that much range if we want to use them from our bases in AP or Leh to fly deep into chinese territory or the East cost major cities ..We need to bring limited Multi Role fighters and invest on some Strategic bombers very badly and urgently this will be the need if we are thinking to take the war into chinese mainland and create some damage ..Chinese have advantage here as they had build some many bases near to our LOC in the Tibet region which they can use to strike deep inside our northern and eastern major cities if they were able to cross our Air defences without a scratch and also escape our interceptor fighters ..
1.Need to invest more on the missiles and also on Submarines to take on China .. Pakistan is sufficiently covered now with the current fleet of fighters and our missiles and ships
2.Strategic command has to be created as
@mendosa rightly said move the fighters to Army aviation and airforce should hold on to the Bigger Multirole fighters.
3.Cross utilisation of resources has to be taken with more serious interest ..Why to simply use Airforce for some strike role missions when Army has brahmos missile or other land attack missiles ..
