Guantanamo Bay Naval Base, officially known as Naval Station Guantanamo Bay or NSGB, is a United States military base located on 45 square miles (117 km2) of land and water on the shore of Guantánamo Bay at the southeastern end of Cuba. It has been permanently leased to the United States since 1903 as a coaling station and naval base, making it the oldest overseas U.S. naval base in the world. The lease was $2,000 in gold per year until 1934, when the payment was set to match the value in gold in dollars; in 1974, the yearly lease was set to $4,085.
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a minefield which is dangerous to cross.
A demilitarized zone is an area in which treaties or agreements between nations, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a 9-mile wide area between Iraq and Kuwait; Antarctica ; and outer space.
The 1949 Armistice Agreements were signed between Israel and Egypt, Lebanon, Jordan, and Syria. They formally ended the hostilities of the 1948 Arab–Israeli War and also demarcated the Green Line, which separated Arab-controlled territory from Israel until the latter's victory in the 1967 Arab–Israeli War.
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.
A separation barrier or separation wall is a barrier, wall or fence, constructed to limit the movement of people across a certain line or border, or to separate peoples or cultures. A separation barrier that runs along an internationally recognized border is known as a border barrier.
A salient, also known as a bulge, is a battlefield feature that projects into enemy territory. The salient is surrounded by the enemy on multiple sides, making the troops occupying the salient vulnerable. The opponent's front line that borders a salient is referred to as a re-entrant – that is, an angle pointing inwards. A deep salient is vulnerable to being "pinched off" through the base, and this will result in a pocket in which the forces in the salient become isolated and without a supply line. On the other hand, a breakout of the forces within the salient through its tip can threaten the rear areas of the opposing forces outside it, leaving them open to an attack from behind.
An area denial weapon is a defensive device used to prevent an adversary from occupying or traversing an area of land, sea or air. The specific method used does not have to be totally effective in preventing passage as long as it is sufficient to severely restrict, slow down, or endanger the opponent. Some area denial weapons pose long-lasting risks to anyone entering the area, specifically to civilians, and thus are often controversial. An area denial weapon can be part of an anti-access/area denial (A2/AD) strategy.
The Armistice of 11 November 1918 was the armistice signed at Le Francport near Compiègne that ended fighting on land, sea, and air in World War I between the Entente and their last remaining opponent, Germany. Previous armistices had been agreed with Bulgaria, the Ottoman Empire and Austria-Hungary. It was concluded after the German government sent a message to American president Woodrow Wilson to negotiate terms on the basis of a recent speech of his and the earlier declared "Fourteen Points", which later became the basis of the German surrender at the Paris Peace Conference, which took place the following year.
The Green Line, (pre-)1967 border, or 1949 Armistice border, is the demarcation line set out in the 1949 Armistice Agreements between the armies of Israel and those of its neighbors after the 1948 Arab–Israeli War. It served as the de facto borders of the State of Israel from 1949 until the Six-Day War in 1967.
In international relations, a concession is a "synallagmatic act by which a State transfers the exercise of rights or functions proper to itself to a foreign private test which, in turn, participates in the performance of public functions and thus gains a privileged position vis-a-vis other private law subjects within the jurisdiction of the State concerned." International concessions are not defined in international law and do not generally fall under it. Rather, they are governed by the municipal law of the conceding state. There may, however, be a law of succession for such concessions, whereby the concession is continued even when the conceding state ceases to exist.
The Free Zone or Liberated Territories is a term used by the Polisario Front government of the Sahrawi Arab Democratic Republic, a partially recognized sovereign state in the western Maghreb, to describe the part of Western Sahara that lies to the east of a 2,200-kilometre (1,400 mi) border wall flanked by a minefield, often referred as the Berm, and to the west and north of the borders with Algeria and Mauritania, respectively. It is controlled by the Sahrawi Arab Democratic Republic, as opposed to the area to the west of the Berm, which is controlled by Morocco as part of its Southern Provinces. Both states claim the entirety of Western Sahara as their territory.
Dragon's teeth are square-pyramidal fortifications of reinforced concrete first used during the Second World War to impede the movement of tanks and mechanised infantry. The idea was to slow down and channel tanks into killing zones where they could easily be disposed of by anti-tank weapons.
An international zone is any area not fully subject to the border control policies of the state in which it is located. There are several types of international zones ranging from special economic zones and sterile zones at ports of entry exempt from customs rules to concessions over which administration is ceded to one or more foreign states. International zones may also maintain distinct visa policies from the rest of the surrounding state.
Involuntary park is a neologism coined by science fiction author and environmentalist Bruce Sterling to describe previously inhabited areas that for environmental, economic, or political reasons have, in Sterling's words, "lost their value for technological instrumentalism" and been allowed to return to an overgrown, feral state.
Peter the Great's Naval Fortress or the Tallinn-Porkkala defence station was a Russian fortification line, which aimed to block access to the Russian capital Saint Petersburg via the sea. The plans for the fortress included heavy coastal artillery pieces along the northern and southern shores of the Gulf of Finland. The emphasis was put on the defenses of the gulf's narrowest point, between Porkkala, and Tallinn,. This was a strategic point, as the two fortresses of Mäkiluoto and Naissaar were only 36 kilometers apart. The coastal artillery had a range of about 25 kilometers and could thus "close" the gap between the shores, trapping enemy ships in a crossfire. Furthermore, a new major naval base was constructed in Tallinn.
Operation Before the Dawn was the first of the three costly human-wave attacks of 1983 in the Amarah area 200 kilometers southeast of Baghdad. It was launched by Iran.
The 1949–1956 Palestinian exodus was the continuation of the 1948 exodus of Palestinian Arabs from Israeli-controlled territory after the signing of the ceasefire agreements. This period of the exodus was characterised predominantly by forced expulsion during the consolidation of the state of Israel and ever increasing tension along the ceasefire lines ultimately leading to the 1956 Suez Crisis.
The Iron Curtain was the political boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1991. The term symbolizes the efforts by the Soviet Union (USSR) to block itself and its satellite states from open contact with the West, its allies and neutral states. On the east side of the Iron Curtain were the countries that were connected to or influenced by the Soviet Union, while on the west side were the countries that were NATO members, or connected to or influenced by the United States; or nominally neutral. Separate international economic and military alliances were developed on each side of the Iron Curtain. It later became a term for the 7,000-kilometre-long (4,300 mi) physical barrier of fences, walls, minefields, and watchtowers that divided the "east" and "west". The Berlin Wall was also part of this physical barrier.
The Line of Contact was the line of military control which separated Armenian forces and the Azerbaijan Armed Forces from the end of the First Nagorno-Karabakh war until the 2020 Nagorno-Karabakh ceasefire agreement.
