Too much chest thumping but little knowledge of how war were / would be fought between Pakistan and India.
K-15 is not PGM, its a SLBM, PA also have capability to use BMs as you mentioned.
First of all,the K 15 also has a land version,it's called Shaurya in case you did not know.In fact,it was induct even before the testing of the sub launched version was completed!!And secondly,it's not even a ballistic missile,the reason??Simple,cause it doesn't actually follow a ballistic flight path in the first place!!The truth is that Shaurya and the Sagarika has been wrongly reported as being a ballistic missile for long by the ill informed reporters,when in reality,it's a direct Indian analogous to the Russian Iskander M!!
The fact is,you are the one who indulges in breast thumping more than often without any real knowledge!!
