Cassie went to the Lunarian, Martian, and Venusian colonies when her Marines took up posts on those bases. Then she went to the asteroids, moons, and dwarf planets of the Outer System. She soon became one of the best zero and low-gee combat assistants in existence, and continued to build on that proficiency as humanity traveled to the stars. Her ability to coordinate Marine operations in those harsh environments has been integral to American dominance in small unit actions all over Terran space and beyond. Even she can’t say how many Marine lives she’s saved over the centuries, but her Marines are happy to take her into action any day of the week. However long or short the week is on the planets, moons, or asteroids they are traveling to that day.
