Fun, Mandatory: When the 1sg or CO (or their spouses) decide that the company's spouses and children are going to have a day set aside for them to have a family oriented even, and you are "invited" (I.E. no choice). you may not leave until the day is over, even though you live in the barracks and have no dependents of your own.
Nah man, CO has us on a Mandatory Fun Day today at 7:00 am.
