Major General Sharon Nesmith has been appointed as the next Deputy Chief of the General Staff and becomes the first female Army officer in the rank of Lieutenant General.
Her appointment has been approved by the Queen and she will begin her new role in August.
Maj Gen Nesmith became the Army's first female officer to command at two-star level, upon her appointment to General Officer Commanding (GOC) Army Recruiting and Initial Training Command in January 2021.
In her role as GOC, she oversaw the recruitment and training of more than 35,000 regular and reserve officers and soldiers across 280 courses each year, the Army said.
Maj Gen Nesmith was also responsible for 5,350 people working in the UK and abroad as part of the organisation, it added.
Maj Gen Nesmith said: "I feel deeply honoured to be appointed as the Deputy Chief of the General Staff at such a pivotal time for the British Army – I look forward to playing my part in leading our Future Soldier transformation to become a more lethal, agile, digitised and expeditionary force."
Chief of the General Staff General Sir Mark Carleton-Smith said: "I am delighted that Sharon Nesmith will be the next Deputy Chief of the General Staff on promotion to Lieutenant General this summer.
"She is the right person at the right time to drive the Army's transformation and she brings a wealth of experience, energy and fresh ideas."
