First of all Pakistan Army is not over stepping, (as asked via the tittle) as it has shown incase of Karchi. Leaving the judgement to the Political leadership though offering help but not directly interfering. Secondly in reply to Hamza100, the Army has carried out a number of welfare projects for the well being of Soldiers as their has been YEAR's OF SOLDIER in Army, where new residence, Quarters with state of the art facilities had been provided to the Soldiers of Pakistan Army. Pakistan Army knows its duties and all has and always will carry out these duties. We respect law and will always help other institutions protect it. Pakistan is our MOTHERLAND and we are all brothers in the fight to save Pakistan.
