Herringbone (formation)
A Herringbone is one type of tactical formation (named after the Herringbone pattern). When in a Herringbone formation, the person at the front of the squad faces forward, while the rest of the squad lines up behind them, facing left and right, alternating as such. The final member of the squad in the herringbone formation faces backwards. When the squad decides to relocate, the person next to the member facing backwards will tap him on the shoulder to make sure he is not left behind. This formation is performed commonly after crossing obstacle An obstacle (also called a barrier, impediment, or stumbling block) is an object, thing, action or situation that causes an obstruction. Different types of obstacles include physical, economic, biopsychosocial, cultural, political, technologic ...s. External links PBase website picture of formation Military organization ...

Tactical Formation
Element: A group of soldiers A tactical formation (or order) is the arrangement or deployment of moving military forces such as infantry, cavalry, AFVs, military aircraft, or naval vessels. Formations were found in tribal societies such as the ''pua rere'' of the Māori,20:32; 27:57, Journal of the Polynesian Society and ancient or medieval formations which include shield walls (''skjaldborg'' in Old Norse), phalanxes (lines of battle in close order), testudo formation and skirmishers. Tactical formations include: * Flight Formations * Box * Coil: Similar to the Herringbone formation, the coil formation allows for 360 degree security while at the halt. This type of formation is also used when refueling aircraft as well as during resupply. Sometimes platoon leaders also use it when briefing to platoon sergeants. Air guards and dismounted fire teams are also in position while this formation is being used. * Column * Echelon * Herringbone * Line * Skirmish * Square * Sta ...

Herringbone Pattern
The herringbone pattern is an arrangement of rectangles used for floor tilings and road pavement, so named for a fancied resemblance to the bones of a fish such as a herring. The blocks can be rectangles or parallelograms. The block edge length ratios are usually 2:1, and sometimes 3:1, but need not be even ratios. The herringbone pattern has a symmetry of wallpaper group pgg, as long as the blocks are not of different color (i.e., considering the borders alone). Herringbone patterns can be found in wallpaper, mosaics, seating, cloth and clothing ( herringbone cloth), shoe tread, security printing, herringbone gears, jewellery, sculpture, and elsewhere. Examples Related tilings As a geometric tessellation, the herringbone pattern is topologically identical to the regular hexagonal tiling. This can be seen if the rectangular blocks are distorted slightly. In parquetry, more casually known as flooring, herringbone patterns can be accomplished in wood, brick, and tile. Su ...

Squad
In military terminology, a squad is among the smallest of military organizations and is led by a non-commissioned officer. NATO and US doctrine define a squad as an organization "larger than a team, but smaller than a section." while US Army doctrine further defines a squad as a "small military unit typically containing two or more fire teams." In US usage, a squad consists of eight to fourteen soldiers, and may be further subdivided into fireteams. Organization NATO The standard NATO symbol for a ''squad'' consists of one single dot (●) placed above a framed unit icon. United States United States Army Historically, a "squad" in the US Army was a sub-unit of a section, consisting of from as few as two soldiers to as many as 12 and was originally used primarily for drill and administrative purposes (e.g., billeting, messing, working parties, etc.). The smallest tactical sub-unit being the section, which was also known as a half-platoon (the platoon itself being a half com ...

Obstacle
An obstacle (also called a barrier, impediment, or stumbling block) is an object, thing, action or situation that causes an obstruction. Different types of obstacles include physical, economic, biopsychosocial, cultural, political, technological and military. Types Physical As physical obstacles, we can enumerate all those physical barriers that block the action and prevent the progress or the achievement of a concrete goal. Examples: * architectural barriers that hinder access to people with reduced mobility; * doors, gates, and access control systems, designed to keep intruders or attackers out; * large objects, fallen trees or collapses through passageways, paths, roads, railroads, waterways or airfields, preventing mobility; * sandbanks, rocks or coral reefs, preventing free navigation; * hills, mountains and weather phenomena preventing the free traffic of aircraft; * meteors, meteorites, micrometeorites, cosmic dust, comets, space debris, strong electromagnetic radiatio ...
