Basically it's a detail platoon of officers that come from all divisions and platoons. Word is they take like 2 from each division, maybe 2 from each platoon in each division, and make the virtual 9th out of that. Then that 9th division gets sent to where ever they are needed for whatever purpose. Not sure if it's on a volunteer basis or if it's going to be the low stat people. But, then again who knows.
