GRUMEC
The Combat Divers Groupment ( pt, Grupamento de Mergulhadores de Combate), abbreviated to GRUMEC, is a special operations and Counterterrorism unit of the Brazilian Navy. The GRUMEC was created in 1974 and is subordinate to the Submarine Force, which provides the primary means of transport for combat diver missions. GRUMEC teams can be transported to the target by a submarine, from which can reach the target by swimming, in kayaks, or in inflatable boats that can be launched from the submarine while it is still under water. The GRUMEC can also reach the target by parachute or helicopter. The function of the GRUMEC is to infiltrate undetected in coastal and riverine environments in order to perform tasks such as reconnaissance, sabotage and the elimination of targets of strategic value. In this sense it is similar to the U.S. Navy SEALs and British Special Boat Service. A member of the force is known as a "MEC", which is an abbreviation of "", meaning "combat diver". Formation ...

Underwater Demolition Team
Underwater Demolition Teams (UDT), or frogmen, were amphibious units created by the United States Navy during World War II with specialized non-tactical missions. They were predecessors of the navy's current SEAL teams. Their primary WWII function began with reconnaissance and underwater demolition of natural or man-made obstacles obstructing amphibious landings. Postwar they transitioned to scuba gear changing their capabilities. With that they came to be considered more elite and tactical during the Korean and Vietnam Wars. UDTs were pioneers in underwater demolition, closed-circuit diving, combat swimming, and midget submarine (dry and wet submersible) operations. They later were tasked with ensuring recovery of space capsules and astronauts after splash down in the Mercury, Gemini and Apollo space flight programs. Commando training was added making them the forerunner to the United States Navy SEAL program that exists today. In 1983, after additional SEAL training, t ...

Private (rank)
A private is a soldier, usually with the lowest rank in many armies. Soldiers with the rank of Private may be conscripts or they may be professional (career) soldiers. The term derives from the medieval term "private soldiers" (a term still used in the British Army), contrasting mercenary soldiers and denoting individuals who were either exclusively hired, conscripted, or mustered into service by a feudal nobleman commanding a battle group of an army. Asia Indonesia In Indonesia, this rank is referred to as '' Tamtama'' (specifically ''Prajurit'' which means soldier), which is the lowest rank in the Indonesian National Armed Forces and special Police Force. In the Indonesian Army, Indonesian Marine Corps, and Indonesian Air Force, "Private" has three levels, which are: Private (''Prajurit Dua''), Private First Class (''Prajurit Satu''), and Master Private (''Prajurit Kepala''). After this rank, the next promotion is to Corporal. File:prada pdh ad.png, Private (''Pra ...

Officer (armed Forces)
An officer is a person who holds a position of authority as a member of an armed force or uniformed service. Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer, or a warrant officer. However, absent contextual qualification, the term typically refers only to a force's ''commissioned officers'', the more senior members who derive their authority from a commission from the head of state. Numbers The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces, and the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, and about 17.2% of the United States armed forces. Historically, however, armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (part ...

HALO Jump
High-altitude military parachuting, or military free fall (MFF), is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion. Two techniques are used: HALO (high altitude – low opening, often called a HALO jump) and HAHO (high altitude – high opening). In the HALO technique, the parachutist opens the parachute at a low altitude after free-falling for a period of time, while in the HAHO technique, the parachutist opens the parachute at a high altitude just a few seconds after jumping from the aircraft. Although HALO techniques were first developed in the 1960s for military use, in recent years HALO parachute designs have been more widely used in non-military applications, including as a form of skydiving. In military operations, HALO is also used for delivering equipment, supplies, or personnel, while HAHO is generally used exclusively for personn ...

Bomb Disposal
Bomb disposal is an explosives engineering profession using the process by which hazardous explosive devices are rendered safe. ''Bomb disposal'' is an all-encompassing term to describe the separate, but interrelated functions in the military fields of explosive ordnance disposal (EOD) and improvised explosive device disposal (IEDD), and the public safety roles of public safety bomb disposal (PSBD) and the bomb squad. History The first professional civilian bomb squad was established by Sir Vivian Dering Majendie. As a Major in the Royal Artillery, Majendie investigated an explosion on 2 October 1874 in the Regent's Canal, when the barge 'Tilbury', carrying six barrels of petroleum and five tons of gunpowder, blew up, killing the crew and destroying Macclesfield Bridge and cages at nearby London Zoo. In 1875, he framed The Explosives Act, the first modern legislation for explosives control. He also pioneered many bomb disposal techniques, including remote methods for the ha ...
