At the command _attention_ the pieces are brought to the right shoulder and the cadenced step in quick time is resumed. _TO DIMINISH THE FRONT OF A COLUMN OF SQUADS._ 194. Being in column of squads: 1. _Right (left) by twos_, 2. _MARCH_. At the command _march_ all files except the two right files of the leading squad execute _in place halt_; the two left files of the leading squad oblique to the right when disengaged and follow the right files at the shortest practicable distance. The remaining squads follow successively in like manner. (_C.I.D.R., No. 2._) 195. Being in column of squads or twos: 1. _Right (left) by file_, 2. _MARCH_. At the command _march_, all files execute _in place halt_ except the right file of the leading two or squad. The left file or files of the leading two or squad oblique successively to the right when disengaged and each follows the file on its right at the shortest practicable distance. The remaining twos or squads follow successively in like manner. (_C.I.D.R., No. 2._) 196. Being in column of files or twos, to form column of squads; or, being in column of files, to form column of twos: 1. _Squads (Twos), right (left) front into line_, 2. _MARCH_. At the command _march_, the leading file or files halt. The remainder of the squad, or two, obliques to the right and halts on line with the leading file or files. The remaining squads or twos close up and successively form in rear of the first in like manner. The movement described in this paragraph will be ordered _right_ or _left_, so as to restore the files to their normal relative positions in the two or squad. 197. The movements prescribed in the three preceding paragraphs are difficult of execution at attention and have no value as disciplinary exercises. 198. Marching by twos or files can not be executed without serious delay and waste of road space. Every reasonable precaution will be taken to obviate the necessity for these formations. EXTENDED ORDER. _Rules for Deployment._ 199. The command _guide right (left_ or _center)_ indicates the base squad for the deployment; if in line it designates the actual _right (left_ or _center)_ squad; if in column the command _guide right (left)_ designates the _leading_ squad, and the command _guide center_ designates the _center_ squad. After the deployment is completed, the guide is _center_ without command, unless otherwise ordered. 200. At the preparatory command for forming skirmish line, from either column of squads or line, each squad leader (except the leader of the base squad, when his squad does not advance), cautions his squad, _follow me_ or _by the right (left) flank_, as the case may be; at the command _march_, he steps in front of his squad and leads it to its place in line.
