Subordinary, or Subordinate Ordinary. In heraldry, a name given to a certain class of charges mostly formed of straight or curved lines. Heralds vary a little in their enumeration, but the following are generally held to come within this category: the Bordure, the Orle, the Tressure, the Flanche, the Pile, the Pall, the Quarter, the Canton, the Gyron, the Fret, the Inescutcheon, the Lozenge, the Fusil, and the Mascle. Some heraldic writers account the Pile an ordinary, and the diminutives of the ordinaries are sometimes ranked as subordinaries.

Subordination. A perfect submission to the orders of superiors; a perfect dependence, regulated by the rights and duties of every military man, from the soldier to the general. Subordination should show the spirit of the chief in all the members; and this single idea, which is manifest to the dullest apprehension, suffices to show its importance. Without subordination it is impossible that a corps can support itself; that its motions can be directed, order established, or the service carried on. In effect, it is subordination that gives a soul and harmony to the service; it adds strength to authority, and merit to obedience; and while it secures the efficacy of command, reflects honor upon its execution. It is subordination which prevents every disorder, and procures every advantage to an army.

Subsidy. A stipulated sum of money, paid by one prince to another in pursuance of a treaty of alliance for offensive or defensive war. Subsidiary troops, are the troops of a nation assisting those of another, for a given sum or subsidy.

Subsist. To support with provisions; to feed; to maintain.
