Grow-up man,
MIG-21 & MIG-27 are the plane which were shot down by manpads.
None of MIRAG & JAGUAR was shot down by them.
Now few points...
These plane are in low altitude recogniz mission, & very old platform & that region is also Himalayan.
Now nearly all fighters are able to drop laser bomb in IAF & war is not just concern in J&K.
So if you are leaving your all air defense onto manpads & on fighters, than only god can save you.
Also manpads for base defense in very unlikely, I never heard like this before. They just provide very low altitude safeguard(max 4 km) & only useful for infantry where CAS is immediate threat.
I recommend you read before you post something like "Grow up man". Read the first word he wrote in his comment. He's pretty much saying the same thing you did.
