The only difference between the divisions of the field message and the field order, then, is that the latter contains in certain orders _The Distribution of Troops_. THE HEADING.—The heading contains: THE TITLE OR NAME OF ISSUING OFFICER’S COMMAND. THE PLACE. THE DATE. THE HOUR OF ISSUE. THE NUMBER OF THE ORDER. THE REFERENCE TO MAP USED. The _Title_ or _Name_ corresponds to the _Name_ of Sending Detachment in the field message. But a title is the name applied to the temporary duty of a command, such as, “Advance Guard, Det. 21st Div.,” whereas the name itself might be “162d Inf., Det. 21st Div.” _The Place_ does not need to be given so specifically as in the field message, because the command issuing a field order takes up much more space than a reconnaissance party. The _Date_ and _Hour of Issue_ are written as in the field message. Field Orders are numbered in sequence usually annually. The _Reference_ to _Map Used_ is placed immediately below the number. The Heading of a field order would appear thus: Field Orders: Det. 21st Div., 12th Corps, No. 22 Leavenworth, Kansas, (Geological Survey Sheet) 9 Dec. 28, 8-15 p. m. THE DISTRIBUTION OF TROOPS.—“The distribution of troops shows the tactical components into which a command is divided (advance guard, main body, etc.) and the troops assigned to each. It is generally used in march orders and in the first field order applying to a command newly created or organized. In other cases it is usually more convenient to name the troops in the body of the order, where their duties are prescribed. When a ‘distribution’ is used, it is headed ‘Troops,’ and in written or printed orders is placed on the left of _The Body_, occupying about one-third of the page. The tactical components are marked with lettered subheads (a), (b), etc., the troops listed under each performing the task prescribed in the similarly marked paragraph of the body of the order. When orders are dictated or sent by wire or signals, the distribution of troops (if used) is given immediately after paragraph 2, without number.”[10] In orders for a regiment and smaller bodies the _Distribution_ of _Troops_ is usually omitted. The Distribution of Troops in a field order would appear thus: _Troops._ (a) Independent Cavalry: Col. Adams. 1st & 2d Sqs. 1st Cav. (less one troop) (b) Advance Guard: Col. Byron. 1st Inf., 1st Cav., Btry. B, 5th F. A. Det. Co. A, Engrs. Det. Amb. Co. No. 1. (c) Main Body, in order of march: 1st Bn, 2d Inf. 1st Bn, 5th F. A. (less 1 btry). 1st Brig. (less 1st Inf. and 1st Bn. 2d Inf.). 4th Inf. Co. A, Engrs. (less det.). Amb. Co. No. 1 (less det.). 1st F. Hosp. (d) Signal Troops: Lieut. Dash. 1 plat., Co. A.
