Position

 

any one of several basic positions of the legs and arms in classical dance. The positions determine the harmonious arrangement of the body in space, assure the proper execution of the dance step, and create the gracefulness and expressiveness of the dance.

There are five positions of the feet. In the first, the feet, with heels touching, have the toes turned outward, forming a straight line on the floor. In the second, the heels of the turned-out legs are placed the length of a foot apart. In the third, the feet partially adjoin one another. In the fourth, the turned-out feet are parallel to each other and separated by a distance of one foot. In the fifth, the feet are closed with the heel of one foot touching the toe of the other.

There are three positions of the arms. In the first, the rounded arms are raised to the level of the diaphragm; in the second, they are extended to either side at shoulder level; and in the third, they are raised over the head. Numerous other positions are formed from the basic one.

Position

 

a zone, or sector, of the terrain that troops are occupying or are preparing to occupy.

Positions are, as a rule, set up by the engineers and form an integral part of deeply echeloned defense zones, in which they are distributed in a definite order along the front and in depth. The main element of every position is usually the defense areas or strongpoints of the defending elements connected by a unified system of fire and obstacles. Each position is equipped with foxholes, bunkers, covers, and if there is time, fire trenches that can be linked by communication trenches. This provides concealment of the disposition of the men and the means of fire at the position, protection from enemy fire, and better opportunities for maneuvering along the front and in depth. Troops also prepare firing positions for machine guns, artillery, mortars, antitank guided missiles, tanks, self-propelled gunmounts, and other means of fire, as well as launching positions for the rocket forces. Intermediate and switch positions may be organized in the depth of the defense. They prevent the advance of the enemy and usually serve as lines of deployment for reserves before they mount a counterattack.

To mislead the enemy concerning the actual location of the main line of resistance, a forward position may be created on several of the most important axes. Moreover, dummy positions may be set up in the depth of the defense, as well as reserve and temporary positions for the maneuver of elements and means of fire in combat. If there is no forward position, a combat security position is created to protect the first position of the main defense zone from surprise enemy attack and to hinder enemy reconnaissance. In preparing for an offensive, attack and assembly positions are organized in the area of departure for elements of motorized rifle and tank troops, as well as launching positions for the rocket troops and firing positions for artillery, mortars, and other means of fire. During an offensive, the troops occupy and organize positions to consolidate the captured terrain.

Units and ships of the navy also take up attack positions prior to combat. Mine-artillery positions may be organized in coastal regions.
