From ‘The psychology of drill’,
The Spectator, 20 February 1915:


One is tempted to divide all men under drill into two classes — the precipitate and the tardy. Every one who has listened to a drill instructor’s words knows that the first part of a command is cautionary. For instance, in ‘Right-turn’ there is a pause between the two words, and the movement to the right takes place on the word ‘turn’.
