WEST FORT HOOD (Now designated Fort Cavazos), Texas – John W. Diem will be promoted into the senior executive service as Civilian Executive Director of the U.S. Army Operational Test Command in a ceremony at its headquarters here Friday at 2 p.m.

Diem will become the only senior executive service member at Fort Hood (Now designated Fort Cavazos), and just as the command’s commander, Brig. Gen. John C. Ulrich has a one-star general officer flown at his events, Diem will uncase an executive service flag of his own.

His new promotion is the federal civilian equivalent to a one-star general officer.

He has been USAOTC’s acting executive director for several months, and before that, he was in charge of the unit’s Test Technology Directorate, which predicts and manages the technology required to collect data from Army systems during operational testing.

He started his career service as an Army commissioned officer and became a test officer in 1982. Since then, he has held many positions up the ladder, each involving the digital testing and simulation aspect of testing Army equipment systems.

A resident of Harker Heights, Diem’s biography can be found at https://www.otc.army.mil/leaders/leaders_ed.html

Media wanting to cover the event should contact the USAOTC Public Affairs Office, at (254) 288-9110, or email: michael.m.novogradac.civ@mail.mil, no later than 10 a.m. Friday. A public affairs escort will meet the media at the West Fort Hood (Now designated Fort Cavazos) Clarke Road gate at 1:15 p.m. Friday.
