red-one report
n.— «An Army regiment apparently does not move an inch before knowing that everyone is accounted for. The process, known as a red-one report, is not unlike what you did in elementary school at the morning bell. And these warriors line up alphabetically about as smoothly as does a sixth grade class.» —“Long road into Iraq is only the beginning” by Bill Johnson in Baghdad, Iraq Rock Mountain News (Denver, Colo.) Nov. 6, 2005. (source: Double-Tongued Dictionary)
