Lt Gen Bipin Rawat on Saturday took over as the 27th chief of the 1.3 million strong Indian Army succeeding Gen Dalbir Singh Suhag, who retired after 42 years of service.
Air Marshal Birender Singh Dhanoa also took charge as the 25th Air Force Chief replacing Anup Raha.
Gen Rawat superseded two senior most Lt Generals, Praveen Bakshi and P M Hariz.
Lt Gen Bakshi, who heads the Kolkata-headquartered Eastern Command, announced "full support" to the new chief and told theatre officers through video conferencing he will continue to lead with "full professional sincerity as hither-to-fore". "I convey my best wishes and full support of Eastern Command to Gen Bipin Rawat on having taken over as the Chief of Army Staff," he said.
Earlier, there was speculation that Lt Gen Bakshi may resign or take premature retirement. He had also met Defence Minister Manohar Parrikar recently.
He requested that speculation and trolling in media and social media should stop and everyone should focus on contributing their best to the betterment of the army and the nation. The Eastern Commander called the new Army chief to congratulate him on taking over the reins of the army.
Speculation is rife that Lt Gen Bakshi may be given the new post of Chief of Defence Staff pertaining which Parrikar will meet Prime Minster Narendra Modi next month.
Sources, however, have indicated that no such development will take place.
Gen Suhag, who superannuated today, said army is prepared to meet any challenge as he thanked the government for "providing a free hand" and implementing the One Rank One Pension scheme.
He said that infiltration bids had increased during the year and the number of terrorists killed was nearly double the previous year.
The General said the army focused on operational preparedness during his tenure.
Suhag said that when he had taken over he had asserted the response of the army to any action against our interest would be immediate, adequate and intense. "Indian Army has done that in the last two-and-a-half years," he said.
Later at noon, he handed over the charge to Rawat, who was commissioned in the Fifth Battalion of the Eleven Gorkha Rifles in December 1978 from IMA, Dehradun. He was awarded the 'Sword of Honour' at the academy.
Earlier in the day, Gen Suhag and Air Chief Marshal Raha paid tributes at Amar Jawan Jyoti and inspected the guard of honour.
