Which of the following is NOT considered a mandatory event in JROTC?

Community service projects are generally encouraged in JROTC as part of the program's emphasis on citizenship, leadership, and community involvement, but they may not be obligatory for all cadets. Mandatory events are typically those that are essential for the formation and functioning of the unit, such as battalion formations, which serve as formal gatherings for important announcements, training, and unit cohesion. In addition, events like the 5K run may be seen as essential for physical fitness training, which is a key component of the JROTC program. Stadium cleanup events may also be mandated to promote responsibility and community spirit. Therefore, while community service is valuable for the development of cadets, it is not universally required in the same way as the other events listed.
