Land Mine
A land mine, or landmine, is an explosive weapon often concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets as they pass over or near it. Land mines are divided into two types: anti-tank mines, which are designed to disable tanks or other vehicles; and anti-personnel mines, designed to injure or kill people. Land mines are typically pressure activated, exploding automatically when stepped on by a person or driven over by a vehicle, though alternative detonation mechanisms are sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Land mines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their indiscriminate nature and their potential to remain dangerous many years after a conflict has ended, harming civilians and the economy. With pressure from a number of campaign gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

When unwanted munitions are found, they are sometimes destroyed in Controlled explosion, controlled explosions, but accidental detonation of even very old explosives might also occur, sometimes with fatal consequences. For example, UXO from World War I continues to be a hazard, with poisonous gas filled munitions still a problem. UXO does not always originate from conflict; areas such as military training bases can also hold significant numbers, even after the area has been abandoned.

After conquering the Liao territory, the Jin launched a Jin–Song Wars, century-long campaign against the Song dynasty (960–1279) based in southern China, whose rulers were ethnically Han Chinese.

Battle Of Bannockburn
The Battle of Bannockburn ( or ) was fought on 23–24 June 1314, between the army of Robert the Bruce, King of Scots, and the army of King Edward II of England, during the First War of Scottish Independence. It was a decisive victory for Robert Bruce and formed a major turning point in the war, which ended 14 years later with the ''de jure'' restoration of Scottish independence under the Treaty of Edinburgh–Northampton. For this reason, the Battle of Bannockburn is widely considered a landmark moment in Scottish history. King Edward II invaded Scotland after Bruce demanded in 1313 that all supporters still loyal to ousted Scottish king John Balliol acknowledge Bruce as their king or lose their lands.

King Edward assembled a formidable force of soldiers to relieve it—the largest army ever to invade Scotland. The English summoned 25,000 infantry soldiers and 2,000 horse ...

Abatis
An abatis, abattis, or abbattis is a field fortification consisting of an obstacle formed (in the modern era) of the branches of trees laid in a row, with the sharpened tops directed outwards, towards the enemy. The trees are usually interlaced or tied with wire. Abatis are used alone or in combination with wire entanglements and other obstacles.
