Army's Top NCO Goes on Twitter to Scold Leaders for Not Testing Units on ACFT Sgt. Maj. of the Army Michael Grinston visits the Maneuver Center of Excellence and Fort Benning to observe one station unit training including the 1st 100 Yards, a training event to teach Warrior Ethos and esprit de corps, Oct. 22, 2020. (Patrick A. Albright/U.S. Army) 1 Mar 2021 The U.S. Army's top enlisted leader unleashed a Twitter rant Sunday morning aimed at shaming unit leaders into administering the Army Combat Fitness Test, or ACFT. Sergeant Major of the Army Michael Grinston told unit leaders in the operational force that they need to make the ACFT a priority so their soldiers' scores can be entered into the Digital Training Management System, or DTMS. That will build more data to evaluate the official replacement for the Army Physical Fitness Test, or APFT.
