Col Beasley thanked wife Kirsten, his parents and the people who had trusted him with the responsibility of command.
Mr Rankin, the Commander-in-Chief of the RBR, added: “Maintaining the traditions of the Regiment while also adapting to change and ensuring excellence requires good leadership.
“And that is why as Commander-in-Chief I am very pleased to be promoting Major Beasley to his new role.”
He said that as Acting Commanding Officer over the Covid-19 outbreak, Major Beasley had “more than earned his spurs” and commended the role played by the RBR in keeping people safe and secure in what has been the longest embodiment of the Regiment since World War II.
Mr Rankin said: “The Regiment can rightly be proud of what is has achieved but, of course, it cannot rest on its laurels as we live in a time of change.
“The Regiment is now an all-volunteer organisation and continues to develop new roles, not least with the establishment of the Bermuda Coast Guard, who have been deployed very effectively on our waters in recent days.”
National Security Minister Wayne Caines said that Col Beasley “day in, day out, he has been unflappable” as the island mobilised to fight the Covid-19 threat and that he had “indeed earned his spurs”.
Mr Caines, a former RBR officer, added that the soldiers under Col Beasley’s command had praised him for his pleasant manner, hard work and fairness.
He said: “I thought these were the most excellent attributes for the leader of our battalion.
“I look forward to seeing the Regiment going from strong to stronger under the leadership of Lieutenant Colonel Beasley.”
Col Beasley, a former regular officer in the Royal Air Force, graduated from the service’s college at RAF Cranwell in 2006 and worked in training and education focused on the North Atlantic Treaty Organisation and in British air policing operations.
He also helped establish the stand-up of RAF flying and ground based squadrons for operations during conflicts in Afghanistan and Iraq before he returned home.
