Question: The Khmer Krom (Khmer: khmaerkroom, Vietnamese: Kho Me Crom) are ethnically Khmer people living in the south western part of Vietnam, where they are recognized as one of Vietnam's fifty-three ethnic minorities. In the Khmer language, Krom means "lower" or "below", as it refers to an area of 89,000 square kilometres (34,363 sq mi) around modern day Saigon and the Mekong Delta, which used to be the southeasternmost territory of the Khmer Empire until its incorporation into Vietnam under the Nguyen lords in the early 18th century. This marks the final stage of the Vietnamese "March to the South" (nam tien).

In the 17th century a weakened Khmer state left the Mekong Delta poorly administered after repeated warfare with Siam. Concurrently Vietnamese refugees fleeing the Trinh-Nguyen War in Vietnam migrated into the area. In 1623 Cambodian king Chey Chettha II (1618-1628) officially sanctioned the Vietnamese immigrants to operate a custom house at Prey Nokor, then a small fishing village. The settlement steadily grew soon becoming a major regional port, attracting even more settlers.  In 1698 the Nguyen Lords of Hue commissioned Nguyen Huu Canh, a Vietnamese noble to organize the territory along Vietnamese administrative lines, thus by de facto detaching it from the Kingdom of Cambodia and incorporating it into Vietnam.  With the loss of the port of Prey Nokor, then renamed Sai Gon, Cambodia's control of the area grew increasingly tenuous while increasing waves of Vietnamese settlers to the Delta isolated the Khmer of the Mekong Delta from the Cambodian kingdom. By 1757 the Vietnamese had absorbed the provinces of Psar Dek (renamed Sa Dec in Vietnamese) on the Mekong itself, and Moat Chrouk (Vietnamized to Chau Doc) on the Bassac River.  Minh Mang enacted assimilation policies upon the Khmer such as forcing them to adopt Sino-Vietnamese surnames, culture, and clothing. Minh Mang sinicized ethnic minorities including the Cambodians, in line with Confucianism as he diffused Vietnamese culture with China's Han civilization using the term Han people Han Ren  for the Vietnamese. Minh Mang declared that "We must hope that their barbarian habits will be subconsciously dissipated, and that they will daily become more infected by Han [Sino-Vietnamese] customs." These policies were directed at the Khmer and hill tribes.  On June 4, 1949 the French President Vincent Auriol signed the accord reincorporating Cochinchina to Vietnam. This was done without consulting the indigenous Khmer-Krom. The legal transfer of control cut Cambodia off from the sea via the Mekong River as the Delta administered by an independent Vietnam. Left within the borders of Vietnam were the communities of Khmer people, nowadays Khmer Krom.

Question: Patrick Daniel Tillman (November 6, 1976 - April 22, 2004) was a professional American football player in the National Football League (NFL) who left his sports career and enlisted in the United States Army in June 2002 in the aftermath of the September 11 attacks. His service in Iraq and Afghanistan, and subsequent death, were the subject of much media attention. Tillman joined the Army Rangers and served several tours in combat before he was killed in the mountains of Afghanistan. At first, the Army reported that Tillman had been killed by enemy fire.

Tillman and his brother Kevin enlisted on May 31, 2002. Kevin gave up the chance of a career in professional baseball as he had already signed to play for the Cleveland Indians. In September 2002, they completed basic training together. The two brothers completed the Ranger Indoctrination Program in late 2002 and were assigned to the 2nd Ranger Battalion in Fort Lewis, Washington. Tillman resided in University Place with his wife before being deployed to Iraq. After participating in the initial invasion of Iraq as part of Operation Iraqi Freedom, in September 2003, they entered Ranger School at Fort Benning, Georgia, and graduated on November 28, 2003.  Tillman was subsequently redeployed to Afghanistan, and based at FOB Salerno. On April 22, 2004, he was initially reported to have been killed by enemy combatants. An Afghan Militia Force allied soldier was also killed in the action. Tillman's platoon leader First Lieutenant David Uthlaut and his radio telephone operator (RTO), 19-year-old Jade Lane, were wounded in the incident. The Army initially claimed that Tillman and his unit were attacked in an apparent ambush on a road outside of the village of Sperah about 25 miles (40 km) southwest of Khost, near the Pakistan border. It was not until after his burial that investigations by the Department of Defense and U.S. Congress were launched, eventually ruling his death as friendly fire.  The Army Special Operations Command initially claimed that there was an exchange with hostile forces. After a lengthy investigation conducted by Brigadier General Gary M. Jones, the U.S. Department of Defense concluded that both the Afghan militia soldier's and Tillman's deaths were due to friendly fire aggravated by the intensity of the firefight.  An investigation by the U.S. Army Criminal Investigation Command (CID) concluded that Tillman and the Afghan militia soldier were killed by friendly fire when one allied group fired upon another in confusion after nearby gunfire was mistakenly believed to be from enemy combatants. The CID Report summary, dated March 19, 2007, stated that:  ...during their movement through the canyon road, Serial 2 [Tillman's platoon had to split up because of a broken Humvee; the parts were called Serial 1 and 2] was ambushed and became engaged in a running gun battle with enemy combatants. Serial 1 [Tillman's portion of the platoon] had just passed through the same canyon without incident and were approximately one kilometer ahead of Serial 2. Upon hearing explosions, gunfire, and sporadic radio communication from Serial 2, Serial 1 dismounted their vehicles and moved on foot, to a more advantageous position to provide overwatch and fire support for Serial 2's movement out of the ambush. Upon exiting the gorge, and despite attempts by Serial 1 to signal a "friendly position", occupants of the lead vehicle of Serial 2 opened fire on Tillman's position, where he was fatally shot.
