It's just a political move by the army. Timing is the most important thing in politics and leadership of Army is better than opposition in this regard. See the timing of announcement via so called (askari zaraiey) not by dj ispr. Moreover, it is not an unprecedented move , the new thing is that the army has admitted presence of corrupt elements, otherwise these kind of compulsory retirements are common but not announced publicly. And all the newspapers and channels reported that they will get pensions and medical and this is a clear proof it is not dismissal.
And those are saying that Army is transparent when it comes to investigation regarding corruption then kindly explain me the procedure of investigation . Transparency means everything is cystal clear from outside. question is that why announcement has been made this time??.. Moreover , its not a civil military issue. What is going on in Baluchistan is a open secret. Army ( FC) , bureaucracy and politicians ; all are facilitating and involved in smuggling .
