Michelle Keegan will return for Our Girl's fourth season.
The former Coronation Street star is reprising her role as Georgie Lane, as filming begins in April.
The fourth season, which will consist of six hour-long episodes, takes place one year after the events in Bangladesh.
Georgie has been promoted to Sergeant, but is reluctant to join 2 Section as they get ready to deploy to Afghanistan.
A near-fatal incident, however, forces her to confront the memories of losing Elvis (Luke Pasqualino) – and she ultimately decides she has to return to Afghanistan to face her own fears.
"Being in Our Girl has been one of the highlights of my career so far," she said. "I feel very lucky to be part of the show, and I'm really excited that it's coming back.
"The audience response has been so positive, and I think Georgie is a character who resonates with viewers. I absolutely love playing the role.
"Be prepared for another incredible series – Georgie's still got unfinished business."
Writer and creator Tony Grounds said: "I'm absolutely delighted that Michelle Keegan will be reprising her role as Georgie Lane for another tour of Our Girl."
In November 2017, Pasqualino reflected on his character's shock death.
"Tony and I sat down and we spoke about potential avenues which we could explore for Elvis's exit," he told Digital Spy at the time.
"We came up with the idea of Elvis and Georgie getting back together – they're gonna get married and they're gonna live that happy life that everybody wanted to see.
"But it wouldn't be good drama if everything was sunshine and rainbows, so we had to snatch it away from the audience."
