Who was actually invited to the banquet? That room seemed a little small to house the whole base, especially since Roxy, Gloria, Denise, CJ, and Jackie were all in attendance and by that I mean all ranks. I mean the exclusive concert at Jackie's house seemed to have more people there.
It was super small. There's no way that Gloria and Jackie would be at the same event unless it was held in a expo hall. Soldiers don't come into contact with Generals except on a "here's an important person come to shake hands because you did something very impressive" basis unless they're on the General's staff. I guess they could have been invited because they helped set things up but if they were inviting everyone from the three star down to the soldiers in the units there would be thousands of people there.
