The positioning of the outer defensive fighting positions of a unit, is circular or triangular, [4] from a bird's-eye view.

One version consists of soldiers forming a wide circle around the soldier in charge (and radioman etc.) with a spacing typically of 3–4 metres between each person (on the circle's circumference).

<span class="mw-page-title-main">Survival, Evasion, Resistance and Escape</span> US military survival training program

Survival, Evasion, Resistance, and Escape (SERE) is a training concept originally developed by the United States during World War II. It is best known by its military acronym and prepares a range of Western forces to survive when evading or being captured. Initially focused on survival skills and evading capture, the curriculum was designed to equip military personnel, particularly pilots, with the necessary skills to survive in hostile environments. The program emphasised the importance of adhering to the military code of conduct and developing techniques for escape from captivity. Following the foundation laid by the British, the U.S. Air Force formally established its own SERE program at the end of World War II and the start of the Cold War. This program was extended to include the Navy and United States Marine Corps and was consolidated within the Air Force during the Korean War (1950–1953) with a greater focus on "resistance training."

<span class="mw-page-title-main">Battle of Kham Duc</span> Part of the Vietnam War (1968)

The Battle of Kham Duc was a major battle of the Vietnam War. The event occurred in Khâm Đức, now district capital of Khâm Đức District, then in Quảng Tín Province, from 10–12 May 1968. During the Tet Offensive of 1968, the People's Army of Vietnam (PAVN) 2nd Division tried to capture Đà Nẵng, but they were defeated in the Battle of Lo Giang by elements of the U.S. 1st Marine Division and the 23rd Infantry Division. PAVN General Chu Huy Mân disengaged from the fight on the outskirts of the city, and pulled the 2nd Division into the mountains to rest, rebuild, and prepare for the next major operation. The US and allied defenders of the Special Forces camp at Khâm Đức, a small district in the north of Quảng Tín, were chosen as the next target for the 2nd Division. Although the Special Forces camp had never been an obstacle to the constant infiltration of PAVN troops around it, the North Vietnamese hoped to attract major US reinforcements away from the lowland populated areas, kill or capture them and film the battle, presumably to make it look like a US Điện Biên Phủ on the eve of the 1st Paris peace conference.
