I think most of you people dont know the terrain of the area. At least my Indian friends dont know and why should they know its not their country.
The possibility that a small unit can take on a much larger unit in area around Kargil, Ladakh, Liah and Drass Batalik area is not unusual. The unit that holds high grounds and has plenty of food and ammunition can do so for a quite some time. These area are extremely rough and vehicular movement, APC or tank movement is not easy and in some cases not possible. Therefore to dislodge enemy you have to move in physically and in this environment the side moving from lower position to higher position usually suffer most.
Remember Indians used all they had to dislodge what a few thousand fighters or soldiers call them whatever. Indians used their state of the art artillery systems, air force and elite commando units for a few thousand of these fighters when they had more than half million soldiers in occupied Kashmir.
Do remember this is not an ordinary battleground numbers dont matter strategy and bold implementation of the strategy is what matters. In the case of Kargil India failed to detect an intrusion into its occupied territory and Pakistan effectively used the strategy they had planned and implemented it with perfection.
So care to tell what was the objective of the plan? Why was PAF not involved? Had Mush and his buddies planned to handle Indian counter attack all among themselves? 4 chaps against a million men.Now just a think more and you will understand how stupid the plan was.
Mush wasted the lifes of hundreds of his men just to fulfill his fantasies by starting an unwanted war.
