Rosetta Calabrese

Despite being born in the megacity of Naples on Earth, Rosetta Calabrese was a natural born survival expert. When she was a young child, her family moved to the minor colony of Gotha, a heavily forested and poorly populated planet. While there, her father taught her various ways of living off the grid, without the support of modern utilities. Due to Gotha's relatively low importance, it was bypassed by the Covenant on their way to Earth, leaving the planet unscathed. In the aftermath of the war, Calabrese wished to visit the new Frontier but lacked the means to do so until 2554, when she was contacted by a member of the private military company Baal Defense Solutions. The company was looking for people with survival experience to help train their contractors and, seeing this as her chance to get to the Frontier, quickly accepted. While working with the members of the newly christened Frontier Division, she took combat lessons from several of the contractors, quickly becoming proficient with a rifle. After she had completed her contract, she requested continued employment with BDS, asking to be assigned to the Frontier Division.
Over the next two years, she proved herself on several combat assignments and was a key factor in the company establishing itself in the Frontier. In 2556, she was granted command of the Frontier Division and reported directly to Frank Holloman, though because she and her deployments were often so far away from any form of central command, she was usually given independent operational control over BDS resources.
