Similarly, General Yahya Khan was the third most senior general when he was made the army chief and General Gul Hassan was also on third number in the list. However, General Tikka Khan was the senior most at the time of his appointment. General Ziaul Haq was given the promotion from eighth number but General Aslam Beg was the senior most at the time of his appointment as army chief. General Waheed Kakar was the fifth on the list. General Jahangir Karamat was the senior most. General Pervez Musharraf was the third most senior when he was made the army chief. General Ashfaq Pervez Kayani was given promotion from second number and General Raheel Sharif from number three.
