I was actually serious. Think about it. As a Muslim your obligation first is to Allah and not any man made constructs like countries, governments, armies, navies etc. You take the Shahada and bear witness to Allah. Not any navy, army, airforce. Between allegiance to a government made by men and Allah a Muslim must stand and choose by the almighty.I can't tell if you're joking or not but be prepared to receive a free 5 day long trip to the "Northern areas of Pakistan"
No Muslim can say a serving officers allegiance to army or navy supercedes his shahada to the almighty. These men who chose the path did so because they stood by Islam first over Pakistan.
