Badges Of The United States Marine Corps
Insignia and badges of the United States Marine Corps are military "badges" issued by the United States Department of the Navy to Marines who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Marine Corps. As described in Chapters 4 and 5 of Marine Corps Uniform Regulations, "badges" are categorized as ''breast insignia'' (worn immediately above ribbons/medals), ''identification badges'' (usually worn at breast pocket level), and ''marksmanship badges'' (worn immediately below ribbons). For the purpose of this article, the term "badge" shall be used exclusively to describe ''identification badges'' and '' marksmanship badges'', and the term "insignia" shall be used for other worn accoutrements, according to the language in Marine Corps Uniform Regulations. The modern-day United States Marine Corps currently maintains the following breast insignia and identification badges: Breast Insignia As per Marine Corps Ass ...

USMC Ribbons And Badges
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as a servic ...

Render Safe Procedure
The render safe procedure (RSP) is the portion of the explosive ordnance disposal procedures involving the application of special explosive ordnance disposal procedures, methods and tools to provide the interruption of functions or separation of essential components of unexploded ordnance (including improvised explosive devices) to prevent an unintended detonation. Overview Ordnance detonations may be broadly categorized as a high order detonation or a low order detonation. A high order detonation is generally an ordnance detonation that results in an explosive ordnance producing a designed/intended explosive yield. A low order detonation is generally a controlled ordnance detonation or a malfunctioned ordnance detonation that results in a significantly lower yield than designed. Render safe procedures and techniques apply to conventional ordnance such as nuclear, chemical, biological and conventional battlefield weapons/ordnance and unconventional ordnance such as improvised e ...

Rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's breathing, exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, and, for covert military use by frogmen or observation of underwater life, eliminating the bubbles produced by an open circuit system and in turn not scaring wildlife being filmed. A rebreather is generally understood to be a portable unit carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supply is limited, such as underwater or in space, where ...

United States Marine Air-Ground Task Force Reconnaissance
The reconnaissance mission within the United States Marine Corps is divided into two distinct but complementary aspects; Marine Division Recon and Force Reconnaissance. The United States Marine Corps Reconnaissance Battalions (or commonly called Marine Division Recon) are the reconnaissance assets of Marine Air-Ground Task Force (MAGTF) that provide division-level ground and amphibious reconnaissance to the Ground Combat Element within the United States Marine Corps. Division reconnaissance teams are employed to observe and report on enemy activity and other information of military significance in close operations. Their capabilities are similar to those of Force Recon, but do not normally insert by parachute, and provide limited direct action, whereas Force Reconnaissance companies perform both deep reconnaissance and direct action operations. Some of these missions are shared by Marine Special Operations Teams, a subordinate part of Marine Special Operations Command (MARSOC) ...

United States Marine Corps Combatant Diver Course
The USMC Combatant Diver Course is taught at the Navy Diving and Salvage Training Center, Naval Support Activity Panama City, Panama City, Florida. Both of the Marine Air-Ground Task Force reconnaissance assets, FMF Recon and MarDiv Recon, widely use combatant diving. During this eight-week course, trainees are introduced to open and closed-circuit diving (using the Dräger LAR-V rebreather), diving physics and medical aid. Most of the training in combatant diving is done at night. The course provides underwater tactical training and the skills needed to successfully conduct underwater navigation for infiltration and exfiltration. The candidates negotiate long distances in open water, infiltrating by surface and sub-surface, learning to deal with the hazards of a surf zone tangle and simulated equipment malfunctions. The combatant divers course combines lecture, demonstration, and practical application in oxygen charging procedures using the USMC Oxygen Transfer Pump S ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been d ...

Biological Warfare
Biological warfare, also known as germ warfare, is the use of biological toxins or infectious agents such as bacteria, viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities ( ''i.e.'' viruses, which are not universally considered "alive"). Entomological (insect) warfare is a subtype of biological warfare. Offensive biological warfare is prohibited under customary international humanitarian law and several international treaties. In particular, the 1972 Biological Weapons Convention (BWC) bans the development, production, acquisition, transfer, stockpiling and use of biological weapons. Therefore, the use of biological agents in armed conflict is a war crime. In contrast, defensive biological research for prophylactic, protective or other peaceful purposes is not proh ...

Chemical Warfare
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear (warfare or weapons), all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons. The use of chemical weapons is prohibited under customary international humanitarian law. Definition Chemical warfare is different from the use of conventional weapons or nuclear weapons because the destructive effects of chemical weapons are not primarily due to any explosive force. The offensive use of living organisms (such as anthrax) is considered biological warfare rather than chemical warfare; however, the use of nonliving toxic products produced by living organisms (e.g. toxins such as botulinum toxin, ricin, and saxitoxin) ''is'' consider ...
