Dehli was part of Punjab so was Jalhandur so both Gen Mush and Gen Zia were (are) punjabi, only non Pujabi general in Pakistan in last sixty year is Gen Mirza Islam beg and that was nature call. Can any one name benagali, Sindhi, Baluch, Hindu, or even Aga Khani general in Pakistan Army? Is their any Shia General in Pakistan Army?
General Musa, Yahya (purportedly) and Air Chief Marshal Mushaf Ali Mir were Shia. Many other Lt. Generals.
Currently, General Shafaat Ullah Shah is Shia. There would be many others that I am not aware of.
Please do not argue based on your emotions.
