True, but this is just a phase of war.
There is method to this madness. There is math and matrix for doctrines and capabilities. PA is already operating on the lower end. Reducing number is a suicide, increasing quality and quantity of equipment is a requirement. WoT was an eye opener for many General, in term of modern training, tactics and equipment for an average soldier.
During surge in Iraq and Afghanistan. US Army and Marine corps repeatedly increased size in phases and for past few years, they are slowly shedding troops by tightening re-enlistment criteria. . Right now US is operation on it's peacetime numbers. US do not have an Enemy of million soldier on it border.
War will happen the day you will reduce your number and capability. It's your deterrence that is keeping the war from not happening.
Totally different geopolitical situation and ground realities. Place UK in Pakistan's neighbourhood, and you guys most probably surrender just looking the odds and enemy numerical advantage. You can destroy a country (from distance) but can never conquer a country without warfight on the ground. Afghanistan is the modern day example. Neither Navy, nor Air Force. No Cyber or Space force will be able to win a war for you. You need boots on the ground. That's where you need number, lot of them. Depending upon size of the country, size and numbers of population center and so on.
So happy to see members understanding the importance of numbers, whether of boots or of tanks or CAS, or ...
This is what allowed the Soviet Union to destroy 80% of the German army. As Stalin put it "quantity has a quality all its own".
They compromised on quality to build equipment of reasonable quality but with the ability to be produced with mass production.
This ability to produce using mass production requires systems to have minimal of parts and complexity.
So the talent then is in designing systems in such a way that they can be mass produced or mass recruited.
Mass recruitment is possible through conscription / volunteer forces supplementing the professional force (and NOT an all professional army). Pak has an advantage over India in this.
India can never conscript effectively due to internal strife and loss of internal unity. Pak can because the average Pakistani is fiercely loyal, brave and willing to fight India.
A simple tank / apc is possible, taking the concept of the T-34 tank and reinventing it in the contemporary setting.
Being able to manufacture tanks rapidly allows one to hold less reserves as production can be started at any point and numbers made up. Why Russia won and Germany didn't.
CAS aircraft can also be mass produced - as the British Hurricane was. The British used metal from cooking utensils to build these planes during the supposed "Battle of Britain". A simple piston engined aircraft that has armour, flies in, drops PGMs, gets out. I will never understand why so many people don't understand the power and effectiveness of air power.
Imagine this. If you had a 1000 CAS aircraft, what would happen to India? Technology exists to allow this to happen. A simple cast aluminum 2-stroke engine and a pulsejet combo allows you to make aircraft (and drones) cheap and easy to manufacture. If one could make drones for 10,000 USD and CAS aircraft for 1 million USD, 100% inhouse, and churn out such weapons in the 1000s if necessary, all calculations and projections change.
When you combine a larger conscript supported army with such tech, you can essentially become a world power, with the caveat of air defence and nuclear weapons (Both of which Pak has).
Think about it.
The world cannot defeat Taliban. What is being envisioned here is something 1000x scarier than the Taliban. Something that can win world wars.
