The combination of a semi-trailer and a tractor truck is called a ''semi-trailer truck'' (also known simply as a "semi-trailer", "tractor trailer", or "semi" in the United States). A large proportion of a semi-trailer's weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly (trailer), dolly, or the B-Train, tail of another trailer. The semi-trailer's weight is semi-supported (half-supported) by its own wheels, at the rear of the semi-trailer. A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable (repositionable) to better distribute load to bearing wheel weight factors. Semi-trailers are more popular for transport than Trailer (vehicle)#Full, full trailers, which have both front and rear axles. Ease of backing i ...

Clandestine Cell System
A clandestine cell system is a method for organizing a group of people, such as resistance fighters, spies, mercenaries, organized crime members, or terrorists, to make it harder for police, military or other hostile groups to catch them. In a cell structure, each cell consists of a relatively small number of people, who know little to no information concerning organization assets (such as member identities) beyond their cell. This limits the harm that can be done to the organization as a whole by any individual cell member defecting, being a mole, being surveilled, or giving up information after being apprehended and interrogated. The structure of a clandestine cell system can range from a strict hierarchy to an extremely distributed organization, depending on the group's ideology, its operational area, the communications technologies available, and the nature of the mission. Criminal organizations, undercover operations, and unconventional warfare units led by special f ...

Quds Force
The Quds Force () is one of five branches of Iran's Islamic Revolutionary Guard Corps (IRGC). It specializes in unconventional warfare and military intelligence operations. U.S. Army's Iraq War General Stanley McChrystal describes the Quds Force as an organization analogous to a combination of the CIA and the Joint Special Operations Command (JSOC) in the United States. Responsible for extraterritorial operations, the Quds Force supports non-state actors in many countries, including Hezbollah, Hamas, Palestinian Islamic Jihad, the Houthi movement, and Shia militias in Iraq, Syria, and Afghanistan. According to Michael Wigginton et al., the Quds Force is "a classic example of state-sponsored terrorism." The Quds Force reports directly to the Supreme Leader of Iran, Ayatollah Khamenei. After Qasem Soleimani was assassinated in a U.S. drone strike, his deputy, Esmail Qaani, replaced him. The U.S. Secretary of State designated the Islamic Revolutionary Guard Corps and ...

Counter Surveillance
Countersurveillance refers to measures that are usually undertaken by the public to prevent surveillance, including covert surveillance. Countersurveillance may include electronic methods such as technical surveillance counter-measures, which is the process of detecting surveillance devices. It can also include covert listening devices, visual surveillance devices, and countersurveillance software to thwart unwanted cybercrime, such as accessing computing and mobile devices for various nefarious reasons (e.g. theft of financial, personal or corporate data). More often than not, countersurveillance will employ a set of actions (countermeasures) that, when followed, reduce the risk of surveillance. Countersurveillance is different from sousveillance (inverse surveillance), as the latter does not necessarily aim to prevent or reduce surveillance. Types Technical surveillance counter-measures Electronic countermeasures Most bugs emit some form of electromagnetic radiation, usually ...
