SOG Knife
The SOG Knife was designed for, and issued to, covert Studies and Observations Group personnel during the Vietnam War. It was unmarked and supposedly untraceable to country of origin or manufacture in order to maintain plausible deniability of covert operators in the event of their death or capture.Pacella, Gerard (2002), ''100 Legendary Knives'', Iola, USA, Krause Publications, p 99. . Design The SOG Knife was designed by Benjamin Baker, the Deputy Chief of the U.S. Counterinsurgency Support Office (CISO). A chrome-moly steel known as SKS-3 was chosen for the blade and hardened to a Rockwell hardness of 55-57. The blade pattern featured a convex false edge on the clip point of a Bowie knife. The stacked leather handle was inspired by a Marbles Gladstone Skinning Knife made in the 1920s owned by Baker, into which finger grooves were molded. The blade was typically parkerized or blackened to reduce glare. This was done so by applying a dark gun-blue finish (similar to those u ...

Vietnam War
The Vietnam War (also known by other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was supported by the United States and other anti-communist allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh took control of North Vietnam, and the U.S. assumed financial and military support for the South Vietnames ...

Plausible Deniability
Plausible deniability is the ability of people, typically senior officials in a formal or informal chain of command, to denial, deny knowledge of or responsibility for any damnable actions committed by members of their organizational hierarchy. They may do so because of a lack or absence of evidence that can confirm their participation, even if they were personally involved in or at least willful blindness, willfully ignorant of the actions. If illegal or otherwise disreputable and unpopular activities become public, high-ranking officials may deny any awareness of such acts to insulate themselves and Blame#Blame shifting, shift the blame onto the agents who carried out the acts, as they are confident that their doubters will be unable to prove otherwise. The lack of evidence to the contrary ostensibly makes the denial plausible (credible), but sometimes, it makes any accusations only cause of action, unactionable. The term typically implies forethought, such as intentionally setti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covert Operation
A covert operation is a military operation intended to conceal the identity of (or allow plausible deniability by) the party that instigated the operation. Covert operations should not be confused with clandestine operations, which are performed in secret and meant to stay secret. Covert operations aim to secretly fulfill their mission objectives without anyone knowing who sponsored or carried out the operation, or in some cases, without anyone knowing that the operation has even occurred. Impact According to a 2018 study by University of Chicago political scientist Austin Carson, covert operations may have the beneficial effect of preventing escalation of disputes into full-blown wars. He argues that keeping military operations secret can limit escalation dynamics, as well as insulate leaders from domestic pressures while simultaneously allowing them communicating their interest to the adversary in keeping a war contained. He finds that covert operations are frequently dete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockwell Scale
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. When testing metals, indentation hardness correlates linearly with tensile strength. History The differential depth hardness measurement was conceived in 1908 by Viennese professor Paul Ludwik in his book ''Die Kegelprobe'' (crudely, "the cone test"). The differential-depth method subtracted out the errors associated with the mechanical imperfections of the system, such as backlash and surface imperfections. The Brinell hardness test, invented in Sweden, was developed earlier – in 1900 – but it was slow, not us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

US Army Special Forces
The United States Army Special Forces (SF), colloquially known as the "Green Berets" due to their distinctive service headgear, are a special operations force of the United States Army. The Green Berets are geared towards nine doctrinal missions: unconventional warfare, foreign internal defense, direct action, counterinsurgency, special reconnaissance, counterterrorism, information operations, counterproliferation of weapons of mass destruction, and security force assistance. The unit emphasizes language, cultural, and training skills in working with foreign troops; recruits are required to learn a foreign language as part of their training and must maintain knowledge of the political, economic, and cultural complexities of the regions in which they are deployed. Other Special Forces missions, known as secondary missions, include combat search and rescue (CSAR), counter-narcotics, hostage rescue, humanitarian assistance, humanitarian demining, information operations, peace ...
