Borders of world

Borders define geographic boundaries of political entities or legal jurisdictions, such as governments, sovereign states, federated states and other subnational entities. Some borders—such as a state's internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Other borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints and border zones may be controlled. Some, mostly contentious, borders may even foster the setting up of buffer zones.
Below Are Some Examples of World Borders or Borders Of The World.

Sniper

Sniper

A sniper is a highly trained marksman who operates alone, in a pair, or with a sniper team to maintain close visual contact with the enemy and engage targets from concealed positions or distances exceeding the detection capabilities of enemy personnel. These sniper teams operate independently, with little combat asset support from their parent units. Snipers typically have highly selective and specialized training and use high-precision/special application rifles and optics, and often have sophisticated communication assets to feed valuable combat information back to their units.

In addition to marksmanship, military snipers are trained in camouflage, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition.Snipers are especially effective when deployed within the terrain of urban warfare, or jungle warfare.

Accuracy For Sniper:-

The key to sniping is accuracy, which applies to both the weapon and the shooter. The weapon should be able to consistently place shots within tight tolerances.The sniper in turn must utilize the weapon to accurately place shots under varying conditions.

A sniper must have the ability to accurately estimate the various factors that influence a bullet's trajectory and point of impact such as: range to the target, wind direction, wind velocity, altitude and elevation of the sniper and the target and ambient temperature. Mistakes in estimation compound over distance and can decrease lethality or cause a shot to miss completely.

Snipers zero their weapons at a target range or in the field. This is the process of adjusting the scope so that the bullet's points-of-impact is at the point-of-aim (centre of scope or scope's cross-hairs) for a specific distance.A rifle and scope should retain its zero as long as possible under all conditions to reduce the need to re-zero during missions.

A sandbag can serve as a useful platform for shooting a sniper rifle, although any soft surface such as a rucksack will steady a rifle and contribute to consistency.In particular, bipods help when firing from a prone position, and enable the firing position to be sustained for an extended period of time. Many police and military sniper rifles come equipped with an adjustable bipod. Makeshift bipods known as shooting sticks can be constructed from items such as tree branches or ski poles.

Range and accuracy vary depending on the cartridge and specific ammunition types that are used.

Army

Army

So Here We See a Short detail about the army.An army in the broadest sense, is the land-based military branch, service branch or armed service of a nation or state. It may also include other branches of the military such as the air force via means of aviation corps. Within a national military force, the word army may also mean a field army an army composed of full-time career soldiers who 'stand over', in other words, who do not disband during times of peace. They differ from army reserves who are activated only during such times as war or natural disasters.

In several countries, the army is officially called the Land Army to differentiate it from an air force called the Air Army, notably France. In such countries, the word "army" on its own retains its connotation of a land force in common usage. The current largest army in the world, by number of active troops, is the People's Liberation Army of China with 2,250,000 active troops and 800,000 reserve personnel followed by the Indian Army with 1,129,000 active troops and 960,000 reserve personnel.

By convention, irregular military is understood in contrast to regular armies which grew slowly from personal bodyguards or elite militia. Regular in this case refers to standardized doctrines, uniforms, organizations, etc. Regular military can also refer to full-time status (standing army), versus reserve or part-time personnel. Other distinctions may separate statutory forces (established under laws such as the National Defence Act), from de facto "non-statutory" forces such as some guerrilla and revolutionary armies. Armies may also be expeditionary (designed for overseas or international deployment) or fencible (designed for – or restricted to – homeland defence).

Army are the national guard of the country.They are also known as national gurdian.

Armies as armed services

• Corps: A Corps usually consists of two or more Divisions and is commanded by a Lieutenant General.
• Division: Each division is commanded by a Major General, and usually holds three Brigades including infantry, artillery, engineers and communications units in addition to logistics (supply and service) support to sustain independent action. Except for the Divisions operating in the mountains, all the Divisions have at least one armored unit, some have even more depending upon their functionality. The basic building block of all ground force combat formations is the infantry division. A typical division would hold three infantry brigades.
• Brigade: A Brigade is under the command of a Brigadier General or sometimes is commanded by a Colonel and comprises three or more Battalions of different units depending on its functionality. An independent brigade would be one that primarily consists of an artillery unit, an infantry unit, an armour unit and logistics to support its actions. Such a brigade is not part of any division and is under direct command of a corps.
• Battalion: Each battalion is commanded by a Colonel or sometimes by Lieutenant Colonel who commands roughly 500 to 750 soldiers. This number varies depending on the functionality of the regiment. A battalion comprises 3–5 companies (3 rifle companies, a fire support company and headquarters company) or its functional equivalent such as batteries (artillery) or squadrons (armour and cavalry), each under the command of a Major. The Company can be divided into platoons, each of which can again be divided into sections or squads (Terminology is nationality and even unit specific)

• Field army

  A field army is composed of a headquarters, army troops, a variable number of corps, typically between three to four, and a variable number of divisions, also between three to four. A battle is influenced at the Field Army level by transferring divisions and reinforcements from one corps to another to increase the pressure on the enemy at a critical point. Field armies are controlled by a General or Lieutenant General.
