Stuxnet is a malicious computer worm, first uncovered in 2010, thought to have been in development since at least 2005. Stuxnet targets supervisory control and data acquisition (SCADA) systems and is believed to be responsible for causing substantial damage to the nuclear program of Iran. Although neither country has openly admitted responsibility, the worm is widely understood to be a cyberweapon built jointly by the United States and Israel.
Stuxnet specifically targets programmable logic controllers (PLCs), which allow the automation of electromechanical processes such as those used to control machinery and industrial processes including gas centrifuges for separating nuclear material. Exploiting four zero-day flaws, Stuxnet functions by targeting machines using the Microsoft Windows operating system and networks, then seeking out Siemens Step7 software. Stuxnet reportedly compromised Iranian PLCs, collecting information on industrial systems and causing the fast-spinning centrifuges to tear themselves apart. Stuxnet's design and architecture are not domain-specific and it could be tailored as a platform for attacking modern supervisory control and data acquisition (SCADA) and PLC systems (e.g., in factory assembly lines or power plants), most of which are in Europe, Japan, and the US. Stuxnet reportedly ruined almost one-fifth of Iran's nuclear centrifuges. Targeting industrial control systems, the worm infected over 200,000 computers and caused 1,000 machines to physically degrade.
Stuxnet has three modules: a worm that executes all routines related to the main payload of the attack; a link file that automatically executes the propagated copies of the worm; and a rootkit component responsible for hiding all malicious files and processes, to prevent detection of Stuxnet. It is typically introduced to the target environment via an infected USB flash drive, thus crossing any air gap. The worm then propagates across the network, scanning for Siemens Step7 software on computers controlling a PLC. In the absence of either criterion, Stuxnet becomes dormant inside the computer. If both the conditions are fulfilled, Stuxnet introduces the infected rootkit onto the PLC and Step7 software, modifying the code and giving unexpected commands to the PLC while returning a loop of normal operation system values back to the users.
In 2015, Kaspersky Lab noted that the Equation Group had used two of the same zero-day attacks prior to their use in Stuxnet and commented that "the similar type of usage of both exploits together in different computer worms, at around the same time, indicates that the Equation Group and the Stuxnet developers are either the same or working closely together".

Zamburak (Persian: زمبورک), literally meaning wasp, was a specialized form of self-propelled artillery from the early modern period, featuring small cannons fired from swivel-mounts on camels. The operator of a zamburak is known as a zamburakchi. The weapon was used by the gunpowder empires, especially the Iranian empires of the Safavid dynasty, Timurid Empire and Afsharid dynasty, due to the ruggedness of the Iranian Plateau, which made typical transportation of heavy cannons problematic.
The zamburak became a deadly weapon in the 18th century. The Pashtuns used it to deadly effect in the Battle of Gulnabad, routing a numerically superior imperial Safavid army. The zamburak was also used successfully in Nader's Campaigns, when the shah and military genius Nader Shah utilized a zamburak corps in conjunction with a regular artillery corps of conventional cannon to devastating effect in numerous battles such as at the Battle of Damghan (1729), the Battle of Yeghevārd, and the Battle of Karnal.

The Highway of Death (Arabic: طريق الموت ṭarīq al-mawt) is a six-lane highway between Kuwait and Iraq, officially known as Highway 80. It runs from Kuwait City to the border town of Safwan in Iraq and then on to the Iraqi city of Basra. The road was used by Iraqi armored divisions for the 1990 invasion of Kuwait. It was repaired after the Gulf War and used by U.S. and British forces in the initial stages of the 2003 invasion of Iraq.
During the American-led coalition offensive in the Persian Gulf War, American, Canadian, British and French aircraft and ground forces attacked retreating Iraqi military personnel attempting to leave Kuwait on the night of February 26–27, 1991, resulting in the destruction of hundreds of vehicles and the deaths of many of their occupants. Between 1,400 and 2,000 vehicles were hit or abandoned on the main Highway 80 north of Al Jahra.
The scenes of devastation on the road are some of the most recognizable images of the war, and it has been suggested that they were a factor in President George H. W. Bush's decision to declare a cessation of hostilities the next day. Many Iraqi forces successfully escaped across the Euphrates river, and the U.S. Defense Intelligence Agency estimated that upwards of 70,000 to 80,000 troops from defeated divisions in Kuwait might have fled into Basra, evading capture.
Project Babylon was a space gun project commissioned by then Iraqi president Saddam Hussein. It involved building a series of "superguns". The design was based on research from the 1960s Project HARP led by the Canadian artillery expert Gerald Bull. There were most likely four different devices in the program.
The project began in 1988; it was halted in 1990 after Bull was assassinated, and parts of the superguns were seized in transit around Europe. The components that remained in Iraq were destroyed by the United Nations after the 1991 Persian Gulf War.
