Please answer the following question: Information:  - Sousveillance is the recording of an activity by a participant in the activity, typically by way of small wearable or portable personal technologies. The term "sousveillance", coined by Steve Mann, stems from the contrasting French words "sur", meaning "above", and "sous", meaning "below", i.e. "surveillance" denotes the "eye-in-the-sky" watching from above, whereas "sousveillance" denotes bringing the camera or other means of observation down to human level, either physically (mounting cameras on people rather than on buildings), or hierarchically (ordinary people doing the watching, rather than higher authorities or architectures doing the watching).  - The Corps of Royal Marines (RM) is the United Kingdom's amphibious light infantry force, forming part of the Naval Service, along with the Royal Navy. The Royal Marines were formed in 1755 as the Royal Navy's infantry troops. However, the marines can trace their origins back to the formation of the English Army's "Duke of York and Albany's maritime regiment of Foot" at the grounds of the Honourable Artillery Company on 28 October 1664.  - The Honourable Artillery Company (HAC) was incorporated by Royal Charter in 1537 by King Henry VIII and is considered one of the oldest military organisations in the world. Today it is a registered charity whose purpose is to attend to the "better defence of the realm", this purpose is primarily achieved by the support of the HAC Regiment and a detachment of Special Constabulary to the City of London Police. The word "artillery" in "Honourable Artillery Company" does not have the current meaning that is generally associated with it, but dates from a time when in the English language that word meant any projectile, including for example arrows shot from a bow. The equivalent form of words in modern English would be either "Honourable Infantry Company" or "Honourable Military Company."  - Behavior is the range of actions and mannerisms made by individuals, organisms, systems, or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the (inanimate) physical environment. It is the response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.  - The 30 Commando Information Exploitation Group is a Royal Marines unit of the British Armed Forces . The unit resources include communications , information operations , information systems , intelligence , surveillance , and Target Acquisition and Reconnaissance ( ISTAR ) . It is a redesignation of the former brigade headquarters battalion , the UK Landing Force Command Support Group , which was previously known as HQ & Signals Squadron RM. The unit 's title harks back to the original 30 Commando ( which in turn became 30 Assault Unit RM ) , formed in 1942 . This unit was tasked to move ahead of advancing Allied forces , or to undertake covert infiltrations into enemy territory by land , sea or air , to capture much needed intelligence , in the form of codes , documents , equipment or enemy personnel . In 2013 , 30 Commando Information Exploitation Group were granted the freedom of Littlehampton , West Sussex , in honour of the original unit being based in the town during the Second World War .  - The Crown dependencies are three territories of the United Kingdom: the Isle of Man in the Irish Sea, and the Bailiwicks of Jersey and Guernsey in the English Channel. Being independently administered jurisdictions, they do not form part of either the United Kingdom or the British Overseas Territories. They are self-governing possessions of the Crown (defined uniquely in each jurisdiction). Internationally, the dependencies are considered "territories for which the United Kingdom is responsible" rather than as sovereign states. As a result, they are not member states of the Commonwealth of Nations. However, they do have a relationship with the Commonwealth, the European Union, and other international organisations and are members of the BritishIrish Council. They are not part of the European Union (EU), although they are within the EU's customs area.  - The British Armed Forces form the military of the United Kingdom, tasked with defence of the country, its overseas territories, and the Crown dependencies. They also promote the UK's wider interests, support international peacekeeping efforts, and provide humanitarian aid.  - The English Army existed while England was an independent state and was at war with other states, but it was not until the Interregnum and the New Model Army (raised by Parliament to defeat the Royalists in the English Civil War) that England acquired a peacetime professional standing army. At the restoration of the monarchy, Charles II kept a small standing army, formed from elements of the Royalist army in exile and elements of the New Model Army, from which the most senior regular regiments of today's British Army can trace their antecedence. Likewise, Royal Marines can trace their origins back to the formation of the English Army's "Duke of York and Albany's maritime regiment of Foot" at the grounds of the Honourable Artillery Company on 28 October 1664.  - Postal interception is the act of retrieving another person's mail for the purpose of ensuring that the mail is not delivered to the recipient, or to spy on them.  - The military, also called the armed forces, are forces authorized to use deadly force, and weapons, to support the interests of the state and some or all of its citizens. The task of the military is usually defined as defense of the state and its citizens, and the prosecution of war against another state. The military may also have additional sanctioned and non-sanctioned functions within a society, including, the promotion of a political agenda, protecting corporate economic interests, internal population control, construction, emergency services, social ceremonies, and guarding important areas. The military can also function as a discrete subculture within a larger civil society, through the development of separate infrastructures, which may include housing, schools, utilities, food production and banking.  - The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a "network of networks" that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.  - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.  - Light infantry (or skirmishers) are soldiers whose job was to provide a skirmishing screen ahead of the main body of infantry, harassing and delaying the enemy advance. Light infantry was distinct from medium, heavy or line infantry. Heavy infantry were dedicated primarily to fighting in tight formations that were the core of large battles. Light infantry fought in open-order, often in close co-ordination with heavy infantry, where they could screen the heavy infantry from harassing fire, and the heavy infantry could intervene to protect the light infantry from attacks of enemy heavy infantry or cavalry. Heavy infantry originally had heavier arms and more armour than light infantry, but this distinction was lost as the use of armour declined and gunpowder weapons became standardized.  - Humanitarian aid is material and logistic assistance to people in need. It is usually short-term help until the long-term help by government and other institutions replaces it. Among the people in need belong homeless, refugees, victims of natural disasters, wars and famines. The primary purpose of humanitarian aid is to save lives, reduce suffering and respect to human dignity. Humanitarian aid is material or logistical assistance provided for humanitarian purposes, typically in response to humanitarian crises including natural disasters and man-made disaster. The primary objective of humanitarian aid is to save lives, alleviate suffering, and maintain human dignity. It may therefore be distinguished from development aid, which seeks to address the underlying socioeconomic factors which may have led to a crisis or emergency.  - Peacekeeping refers to activities intended to create conditions that favor lasting peace. Research generally finds that peacekeeping reduces civilian and battlefield deaths and reduces the risk of renewed warfare.  - Surveillance (or ) is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting them. This can include observation from a distance by means of electronic equipment (such as CCTV cameras), or interception of electronically transmitted information (such as Internet traffic or phone calls); and it can include simple, no- or relatively low-technology methods such as human intelligence agents and postal interception. The word "" comes from a French phrase for "watching over" ("sur" means "from above" and "veiller" means "to watch"), and is in contrast to more recent developments such as sousveillance.  - The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service.  - A troop is a military sub-subunit, originally a small formation of cavalry, subordinate to a squadron. In many armies a troop is the equivalent element to the infantry section or platoon. Exceptions are the Royal Horse Artillery and the US Cavalry, where troops are subunits that compare to an infantry company or artillery battery.   - Internet traffic is the flow of data across the Internet.
