Operation Prairie
Operation Prairie was a U.S. military operation in Quảng Trị Province, South Vietnam that sought to eliminate People's Army of Vietnam (PAVN) forces south of the Demilitarized Zone (DMZ). Over the course of late 1965 and early 1966 the Viet Cong (VC) and the PAVN intensified their military threat along the DMZ. The tactical goal of these incursions was to draw United States military forces away from cities and towns. Operation Hastings, a series of actions in defense of the DMZ, lasted from 15 July to 3 August 1966. It was considered a strategic success. Operation Prairie was conceived as a larger, longer mission covering the same areas along the DMZ. It commenced on 3August 1966 and lasted for six months. The majority of the activities were conducted by the 3rd Marine Division in the Con Thien and Gio Linh regions with the main objective of stopping the PAVN 324B Division from crossing the demilitarized zone and invading Quang Tri Province. Various units engaged in fierc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tet Offensive
The Tet Offensive was a major escalation and one of the largest military campaigns of the Vietnam War. It was launched on January 30, 1968 by forces of the Viet Cong (VC) and North Vietnamese People's Army of Vietnam (PAVN) against the forces of the South Vietnamese Army of the Republic of Vietnam (ARVN), the United States Armed Forces and their allies. It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam. The name is the truncated version of the Lunar New Year festival name in Vietnamese, Tết Nguyên Đán, with the offense chosen during a holiday period as most ARVN personnel were on leave. The purpose of the wide-scale offensive by the Hanoi Politburo was to trigger political instability, in a belief that mass armed assault on urban centers would trigger defections and rebellions. The offensive was launched prematurely in the late night hours of 30 January in the I and II Corps Tactical Zones of South V ...

UH-1E Huey
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing 700 shp (520 kW), by 1966, the Lycoming T53-L-13, ...

Cam Lo Combat Base
Calmodulin (CaM) (an abbreviation for calcium-modulated protein) is a multifunctional intermediate calcium-binding messenger protein expressed in all eukaryotic cells. It is an intracellular target of the secondary messenger Ca2+, and the binding of Ca2+ is required for the activation of calmodulin. Once bound to Ca2+, calmodulin acts as part of a calcium signal transduction pathway by modifying its interactions with various target proteins such as kinases or phosphatases. Structure Calmodulin is a small, highly conserved protein that is 148 amino acids long (16.7 kDa). The protein has two approximately symmetrical globular domains (the N- and C- domains) each containing a pair of EF hand motifs separated by a flexible linker region for a total of four Ca2+ binding sites, two in each globular domain. In the Ca2+-free state, the helices that form the four EF-hands are collapsed in a compact orientation, and the central linker is disordered; in the Ca2+-saturated state, th ...

McNamara Line
The McNamara Line, an operational strategy employed by the United States in 1966–1968 during the Vietnam War, aimed to prevent infiltration of South Vietnam by NVA forces from North Vietnam and Laos. Physically, the McNamara Line ran across South Vietnam from Cửa Việt port to Route 9 and to the Laotian border along the Vietnamese Demilitarized Zone (DMZ) till Mường Phìn, Laos. The eastern part included fortified field segments, with Khe Sanh as linchpin, along with stretches where roads and trails were guarded by high-tech acoustic and heat-detecting sensors on the ground and interdicted from the air. Assorted types of mines, including so-called gravel mines, and troops at choke points backed sophisticated electronic surveillance. Named ''the barrier system'' by Robert McNamara (United States Secretary of Defense from 1961 to 1968), it was one of the key elements, along with gradual aerial bombing, of his war strategy in Vietnam.
