DAVENPORT, Iowa -- To illustrate the complexity of the Directorate of Logistics transformation from the Installation Management Command to the Army Sustainment Command, Col. Danny Tilzey, commander of the "Mighty" 407th Army Field Support Brigade, Fort Hood, Texas, took a deck of cards out of his pocket.As he ruffled the cards in front of two people, Tilzey asked each of them to tell him which card they saw. They chose different cards."You say the four of spades and she says the nine of hearts - and it's the same deck of cards," he said. "This is my DOL.""You see the problem," he said, as he began briefing his DOL command and control concept.The command structure and many other issues became clearer during a rehearsal of concept drill that took place Aug. 24-26 at the Radisson Quad City Plaza Hotel in Davenport, Iowa.During the conference, lively discussions took place on a variety of topics, including Commanders Critical Information Requirements (CCIRs), contracting, transportation, food service, and personal property moves.The Army Materiel Command will take operational control of DOL functions in the United States on Oct. 1. ASC, through its AFSBs, will take responsibility for the new logistics mission. Target date for completing the transfer of all DOLs, worldwide, including resources and personnel, is Oct. 1, 2011.More than 160 people from major commands and organizations throughout the Army attended the ROC drill.The ambitious agenda concentrated on regional AFSB and IMCOM logistics issues, said Kathy Acree, ASC lead for the DOL Enterprise Transformation."The main focus is to gain agreement from all of the stakeholders on how we're going to operate 1 October," Acree said.Greg Kuhr, IMCOM G4, executive for logistics, had certain expectations for the conference."Number One, to assess where we are in the process of realigning our DOLs, and then to identify where we could potentially have some issues, and then finally to map out a way ahead," he said. "What do we need to do to prepare for the OPCON relationship, which will be in FY11, and then what do we need to do to prepare for the formal reassignment in FY12 of our DOLs'"The first day of the three-day workshop featured overview briefings by IMCOM and ASC representatives, command and control concepts by the AFSB commanders and a discussion of transportation issues.Tilzey was not the only AFSB commander to brief the group on his command and control concept. Col. Johnny Johnston, 406th AFSB commander, Fort Bragg, N.C., and Col. George Akin, 404th AFSB, Joint Base Lewis-McChord, Wash., also briefed their concepts.Tilzey and Johnston took command of their brigades in July."I think the most important thing that we got out of it is the way we're going to C2, what kind of structure we're going to have to do the C2 of it," Johnston said, referring to the AFSB command and control role in the DOL transformation.During the rest of the conference, attendees worked through a series of vignettes to determine organizational responsibilities in different situations. With the help of the participating directors of logistics and other subject-matter experts, the group identified a list of issues that needed to be resolved before ASC takes operational control of the DOLs. Several breakout sessions also took place to discuss some of the more difficult issues, such as resource management and personnel.The ROC drill is one more step in an ongoing series of meetings to make sure OPCON goes as smoothly as possible."This is an iterative process," Kuhr said. "This is one of several meetings that we'll have. The ASC senior staff is traveling to San Antonio next week, and we'll talk over several issues - the resourcing issues, the personnel issues. So it's just another set of meetings in this process, and I think we're on track. I think things are going very well, and we'll make it happen."
