All-round Defence
All-around defense or perimeter defense is a type of defensive fighting position intended to give military units the ability to repel attacks from any direction. The positioning of the outer defensive fighting positions of a unit, is circular or triangular,http://www.marines.mil/news/publications/Documents/FM%203-21.8%20%20The%20Infantry%20Rifle%20Platoon%20and%20Squad_5.pdf "The trace of the platoon is circular or triangular rather than linear" from a bird's-eye view. One version consists of soldiers forming a wide circle around the soldier in charge (and radioman etc.) with a spacing typically of 3–4 metres between each person (on the circle's circumference). When a group of soldiers relocate as a part of a defensive operation, a perimeter defense can be temporarily maintained without cover.

Defensive Fighting Position
A defensive fighting position (DFP) is a type of earthwork constructed in a military context, generally large enough to accommodate anything from one soldier to a fire team (or similar sized unit). Terminology Tobruk type positions are named after the system of defensive positions constructed, initially, by the Italian Army at Tobruk, Libya. After Tobruk fell to the Allies in January 1941, the existing positions were modified and significantly expanded by the Australian Army which, along with other Allied forces, reused them in the Siege of Tobruk. A foxhole is one type of defensive strategic position. It is a "small pit used for cover, usually for one or two personnel, and so constructed that the occupants can effectively fire from it". It is known more commonly within United States Army slang as a "fighting position" or as a "ranger grave". It is known as a "fighting hole" in the United States Marine Corps, a "gun-pit" in Australian Army terminology, and a "fighting pit ...

Bird's-eye View
A bird's-eye view is an elevated view of an object or location from a very steep viewing angle, creating a perspective as if the observer were a bird in flight looking downwards. Bird's-eye views can be an aerial photograph, but also a drawing, and are often used in the making of blueprints, floor plans and maps. Before crewed flight was common, the term "bird's eye" was used to distinguish views drawn from direct observation at high vantage locations (e.g. a mountain or tower), from those constructed from an imagined bird's perspectives. Bird's eye views as a genre have existed since classical times. They were significantly popular in the mid-to-late 19th century in the United States and Europe as photographic prints. Terminology The terms aerial view and aerial viewpoint are also sometimes used synonymous with bird's-eye view. The term ''aerial view'' can refer to any view from a great height, even at a wide angle, as for example when looking sideways from an airplan ...

Radioman
Radioman (RM) was a rating for United States Navy and United States Coast Guard enlisted personnel, specializing in communications technology. History of the rating The rating was created originally in 1921. In 1997, under the direction of Chief of Naval Operations Admiral Mike Boorda, the rating merged with the Data Processing Technician (DP) rating to form the Information Systems Technician (IT) rating. Both Radiomen and Data Processing Technicians in the Navy had to undergo general rate training and take a computer-based exam in order to be designated under the new IT rating. In 1996, the Submarine force merged Radioman with Electronics Technicians/ Electronic Warfare Specialist. The Coast Guard rating was renamed Telecommunications Specialist (TC) in 1995, which split in July 2003 to make up the Information System Technician (IT) and Operations Specialist (OS) ratings. Scope of work The Radiomen of the US Navy were responsible for transmitting and receiving radio signals ...

Circumference
In geometry, the circumference (from Latin ''circumferens'', meaning "carrying around") is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure. Circumference may also refer to the circle itself, that is, the locus corresponding to the edge of a disk. The is the circumference, or length, of any one of its great circles. Circle The circumference of a circle is the distance around it, but if, as in many elementary treatments, distance is defined in terms of straight lines, this cannot be used as a definition. Under these circumstances, the circumference of a circle may be defined as the limit of the perimeters of inscribed regular polygons as the number of sides increases without bound. The term circumference is used when measuring physical objects, as well as when considering abstract g ...

Infantry Tactics
Infantry tactics are the combination of military concepts and methods used by infantry to achieve tactical objectives during combat. The role of the infantry on the battlefield is, typically, to close with and engage the enemy, and hold territorial objectives; infantry tactics are the means by which this is achieved. Infantry commonly makes up the largest proportion of an army's fighting strength, and consequently often suffers the heaviest casualties. Throughout history, infantrymen have sought to minimise their losses in both attack and defence through effective tactics. (''For a wider view of battle and theater tactics see: Military strategy)'' Infantry tactics are the oldest method of warfare and span all eras. In different periods, the prevailing technology of the day has had an important impact on infantry tactics. In the opposite direction, tactical methods can encourage the development of particular technologies. Similarly, as weapons and tactics evolve, so do the tacti ...

List Of Military Tactics
This article contains a list of military tactics. The meaning of the phrase is context sensitive, and has varied over time, like the difference between "strategy" and "tactics". General * Exploiting prevailing weather – the tactical use of weather as a force multiplier has influenced many important battles throughout history, such as the Battle of Waterloo. * Fire attacks – reconnaissance by fire is used by apprehensive soldiers when they suspect the enemy is nearby. * Force concentration – the practice of concentrating a military force against a portion of an enemy force. * Night combat – combat that takes place at night. It often requires more preparation than combat during daylight and can provide significant tactical advantages and disadvantages to both the attacker and defender. * Reconnaissance – a mission to obtain information by visual observation or other detection methods, about the activities and resources of the enemy or potential enemy, or about the me ...

Fortification
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they act ...
