When not training for combat the marines aboard the Bonaventure are left to their own devices. Many pursue physical interests, such as grav-ball or zero-g acrobatics. Others, however, tend to prefer more technical or scholarly occupations. Here we list the entirety of known projects pioneered by marines, or a cooperative effort between them and other crew members aboard the Bonaventure. While it may not be target practice, their efforts often result in benefitting the corp in other ways, if not Starfleet as a whole.
