In some sense your are right. Pakistani army did not exist in the way of a well-equipped combat force of the day.
However Pak army officers and jawans had tones of experience in the art of modern war-fighting. These officers and jawans had been part of the combat duties against Germans and Japanese in WWII and earned great respect from both the foes and the friends.
The same officers had a lot of experience fighting the tribal anarchists and terrorists in modern day FATA (especially uncouth Waziri trouble makers) and Afghanistan.
So in essence Pak army had all the necessary building blocks of a modern combat force in 1947 as far men are concerned. The only thing needed was the material and a couple of years worth of organizational and logistical setup. No wonder that within few years after 1947, Pakistani army was able to form a cohesive, combat ready modern force. The force that was well respected by UK and US, and the force that was feared by the tribal terrorists at home and abroad (especially Middle East).
Thanks for sharing burqaposhx............
I would like to add that somewhere on the Kashmir front when troops were being gathered for assault against the Pakistan Volunteers.........the Pakistan Armys local Commander used a very innovative tactic of putting a tank track on a Jeep........
He made his soldiers run this Jeep all night to make it sound like Tanks were being brought in to the Battle.......
Next morning When Pakistani Volunteers attacked the Indians had already dispersed and retreated.........expecting a Tank assault....:)
this commanders name ........General Akbar...
