Prime Minister Nawaz Sharif has confirmed Lt Gen Qamar Javed Bajwa as the new Chief of Army Staff (COAS) replacing the outgoing General Raheel Sharif, Waqt News reported.
President Mamnoon Hussain has made the appointment on the advice of Prime Minister Muhammad Nawaz Sharif.
Meanwhile Lt Gen Zubair Hayat has been appointed the Chairman Joint Chief of Staff Committee (CJCSC).
The Defence Ministry’s notification confirms that both Lt Gen Zubair Hayat and Lt Gen Qamar Javed Bajwa have been promoted to the four-star general rank.
Multan Corps Commander Lt Gen Nadeem and Bahawalpur Corps Commander Lt Gen Javed Iqbal Ramday had also been in contention for the COAS post.
Lt Gen Qamar Javed Bajwa has been serving as the Inspector General of the Training and Evaluation.
He has previously served as the Force Commander Gilgit-Baltistan and Rawalpindi Corps Commander.
Since Gen. Bajwa has been posted in Ten Corps thrice, he has good experience of handling affairs in Kashmir. He belongs to the infantry's Baloch Regiment is from the 62nd MPA Long Course.
The army chief is arguably the most influential person in Pakistan, with the military having ruled the country for about half of its 69-year history since independence from Britain and enjoying extensive powers even under civilian administrations.
General Bajwa will likely take charge of the world's sixth-largest army by troop numbers in a formal handover on Tuesday, when General Sharif formally retires.
"On the advice of Pakistani Prime Minister Muhammad Nawaz Sharif, President Mamnoon Hussain has approved the promotion of Lieutenant General Zubair Mehmood Hayat and Lieutenant General Qamar Javed Bajwa," the prime minister's office said.
General Sharif, 60, becomes the first army chief in more than 20 years to step down on time. Several previous military leaders had obtained extensions to their three-year terms.
Though security across Pakistan has vastly improved under General Sharif, with number of reported "terrorist" attacks down, Bajwa will face vast challenges at home and abroad.
Islamic State (IS) is trying to make inroads into the country and militant groups such as the Pakistani Taliban continue to stage large-scale bomb and gun attacks.
Since August, 184 people have been killed in three major attacks in the restive Baluchistan region alone.
There are fears that if violence in Baluchistan escalates it could disrupt work on the road, rail and energy projects central to the $54 billion China-funded economic corridor which aims to link Western China to the Arabian Sea at Pakistan's deepwater port of Gwadar in Baluchistan.
Abroad, Pakistan's relations with the United States, a long-time ally, as well as nuclear-armed rival India, have worsened over the past year.
Little is publicly known about Bajwa. It is also not clear how he would approach sensitive issues such as military-civilian relations or his ideological stance towards India.
The military, in a statement, only sent out a brief army history of Bajwa, who was commissioned in 1980 and was partly educated abroad, including staff college training in Canada and naval post-graduate studies in the United States.
Bajwa had also served abroad, commanding the Pakistan Contingent in Congo, and had spent time commanding infantry divisions.
One cabinet minister told Reuters that Prime Minister Sharif picked Bajwa because of his low-key style, and felt the incoming general would be more willing to cede control of key areas to the civilian government.
"He is essentially a very low-profile person and after our last experience (with General Sharif) this is just a very important consideration; someone who doesn’t want the limelight at all," said the minister, asking not to be named because of the sensitivity of the issue.
When Prime Minister Sharif chose his namesake as army chief in 2013, it was because the general was the most apolitical figure among the candidates, sources close to the premier said at the time.
But once appointed, General Sharif maintained the army's strong influence within Pakistani politics. Though he did not overtly meddle and rarely made public political statements, he was seen as a key player in behind-the-scene decision making.
Analysts say the political tussle is likely to occur again with the new chief, saying that all military leaders have ended up challenging the prime minister's authority in some way once they began to represent the interests of the army.
General Sharif, who hails from a military family, built a huge following among ordinary Pakistanis who saw him as a protector against Islamists, corruption and foreign aggression.
His popularity came on the back of the military operation Zarb-e-Azb, which drove back Pakistani Taliban militants from their tribal strongholds and improved security.
An army-led crackdown in Karachi also drastically reduced crime in the country's biggest city.
But General Sharif's popularity, enhanced by the army's slick media unit, also unnerved members of the ruling PML-N party who were suspicious of efforts to glorify the army chief.
After their final official dinner together on Thursday, Prime Minister Sharif praised the departing general.
"He proved beyond a shadow of doubt that he is one of the finest military leaders of his generation," the prime minister said. "Pakistan today is much safer and stronger than in 2013."
