As a reservist in the past, I can understand it. For reservists only working on the weekends, I understand why they would choose such a possibility, considering that during the week they're working elsewhere anyway and they wouldn't want to lose their employment. But as a full-time NCO...I have a little bit of difficulty understanding this.
What would be the advantage, other than for family reasons, of doing this? He's being punished during the week under the pretense that it would cause confusion.... I don't know why there would be confusion. I can understand if you're a private in the cell. Having worked in civilian prisons, I can understand the relationship that needs to exist, the punishment being that time they spend in jail. But I don't understand why he would still be a soldier during the week. Wouldn't that be like a sentence that would be added, simply giving him the opportunity to be spending time with his family?
