If Shri army chief enjoys such powers how did Ganja managed to kick out two army chiefs in his short miserable rein? You saying that Shri army chief was dumb not to exercise his unlimited powers? bery bery strange! may be Shri Jehangir should consult with Ikram Segal and file a law suite against ganja in Lahore High court. :)
Again you are missing the point, its up to Army Chief what he wanted to do? Make sense? Lets say their are really such a rules or power existed? Will rest of nation should know about it ? or only few power brokers?
Their is secret act in constitution, some says it just regarding secret document or state secrets,..
I don't believe this gibberish Army take over the country with man power, with just 600000 men !..
