The IA definitely has significant experience in COIN, but you have to look at the lower casualty rates in the context of very, very low numbers of insurgents and minimal cross-LoC infiltration and provision of supplies.
While the IA puts the total number of insurgents in Kashmir at between 300 to 800, we had around 500 Taliban in Buner alone, all supplied with excellent communications equipment, mortars, RPG's and other weapons.
The operation in Bajaur alone resulted in 1500 militants killed, and there was a significant number of reinforcements from across the border in support of the Bajaur Taliban (estimates suggest over a thousand) in just that short operation span.
The dynamics in Kashmir and FATA are significantly different, which is why I have always been leery of direct comparisons between the two.
Agnostic
The relatively lower numbers of militants has been achieved over a period of time (and in part due to Musharraf taking steps to curb crossing over). Early 90s there was a time when Sopore was an area which was virtually lost to India. It took time and casualties.
Am not making a direct comparision at all. PA is new in CI grid and as such will take time to adjust and modify its principles and doctrine as also at the same time you have undoubtedly a more robust and determined enemy which has battle experience of more than 3 decades to draw from (as against 2 decades for IA).
There can not be any comparision. I merely meant to state that PA is learning and it shall evolve its doctrine as it gains experience. It will take casualties as mistakes happen and you learn from them and then soon PA itself will be able to sustain high tempo of CI ops with an acceptable casualty rate.
I am still reserved about use of firepower/armour though.
Thanks
