You mean Egypt and Israel? because Pakistan never had and doesn't have experience in large scale wars that involved large scale Land, air, and navy warfare all at the same time with huge numbers, Pakistan only had conflicts with India, which at the time of their wars was not and never as strong or experienced or technologically advanced as Israeli military, and not even better than Israel now, which was stronger and better equipped with the most advanced American weapons and better trained than the Egyptians at the time who were only trained by Soviets who didn't train them good, and gave them shitty weapons.
But despite that the Egyptians caused Israel significant losses in 1973 war and got their land back, you can't compare that to the noob conflicts between India and Pakistan (in which Pakistan was never successful at capturing a land, or forcing it politically after, because never achieved a real military victory against India), India was never as strong and experienced as Israel so don't compare Pakistan's military experience in those noob fights against India with the Egyptians fighting one of the most advanced militaries in the world in large scale wars.
That is what we can really call battle hardened.... not Pakistan, which is like a soldier shooting chickens or rats with rifles for 40 years then we call him battle hardened and experienced in combat, that's called a noob combat, not a real combat that can really give you experience against one of the strongest and most advanced and best trained militaries in the world (Israel).
A fight between 300 troops is not a war or a battle hardening experience granting combat. and even Pakistan's big wars with India ended with Pakistani surrender and a decisive Indian victory, so stop all the bullshit, you can't compare experience gained from a fight with a cat to a fight with a lion, that's way technologically and numerically superior to you.
The five years big 1970s operation in Balochistan conflict was only ground troops war.
Pakistan had 145,000 Vs 20,000 Indian, that's 7x more troops than India, lasted for long five years and ended with 3,300 dead Pakistani of 145,000 vs 5,300 dead of 20,000 ,
+ Do you remember what happened to the "battle hardened" Pakistani military in your country (Bangladesh liberation war) ?
Oh now we will talk shit about the battle hardened Abrams, the only tank in the world that proved itself in wars, in it's main role.
