The Battle of Biltine (2006), was an armed confrontation between the Chadian military and armed rebel groups, notably the UFDD. Born in St. Louis, United States, the son of Italian and British immigrants, Amerigo Dumini moved to Italy and in the 1913 he joined the army renouncing to his american citizenship.  During First World War he was in assault troops and severely wounded and decorated.  Then he became active in the Fascio of Florence organized by supporters of Benito Mussolini, taking pride in being referred to as "Sicario del Duce" ("Il Duce's hitman").  He participated in the Sarzana incident on 21 July 1921, leading a column of 300 "squadristi" (Blackshirts) to Sarzana with demands for the liberation of Renato Ricci.  Ricci and other fascists had been arrested following armed confrontation with the "Arditi del Popolo", an antifascist organization created in 1921 by the anarchist Argo Secondari as an offshoot of the "Arditi" movement. The Utah War (1857–1858), also known as the Utah Expedition, Utah Campaign, Buchanan's Blunder, the Mormon War, or the Mormon Rebellion was an armed confrontation between Mormon settlers in the Utah Territory and the armed forces of the United States government.  The confrontation lasted from May 1857 to July 1858.  There were some casualties, mostly non-Mormon civilians.  The war had no notable military battles. The Siege of Menagh Air Base (also spelled "Menegh", "Mannagh", or "Minakh") was an armed confrontation between the Free Syrian Army and aligned Islamist rebel groups on one hand, and the Syrian Armed Forces on the other. The North Hollywood shootout, sometimes also called the Battle of North Hollywood, was an armed confrontation between two heavily armed and armored bank robbers and members of the Los Angeles Police Department (LAPD) in the North Hollywood district of Los Angeles on February 28, 1997.  Both perpetrators were killed, twelve police officers and eight civilians were injured, and numerous vehicles and other property were damaged or destroyed by the nearly 2,000 rounds of ammunition fired by the robbers and police. The 2014 Bundy standoff was an armed confrontation between supporters of cattle rancher Cliven Bundy and law enforcement following a 21-year legal dispute in which the United States Bureau of Land Management (BLM) had obtained court orders directing Bundy to pay over $1 million in withheld grazing fees for Bundy's use of federally owned land adjacent to Bundy's ranch in southeastern Nevada. Isaiah Stillman (1793–15 April 1861) was an American Cavalry Major who led the Illinois militia in the first armed confrontation of the Black Hawk War against Black Hawk's Sauk Indian Band.  The first armed confrontation would be named Battle of Old Man's Creek, but would later be named Stillman's Run after him. Citizens for Constitutional Freedom (C4CF), later also known as People for Constitutional Freedom (P4CF), was the name taken on January 4, 2016, by an armed private U.S. militia that occupied the U.S. Fish and Wildlife Service's Malheur National Wildlife Refuge headquarters in the U.S. state of Oregon from January 2 to February 11, 2016.  The leader of the organization was Ammon Bundy, son of Cliven D. Bundy, who engaged in a standoff with the federal government over grazing rights on federal land. Cliven D. Bundy (born April 29, 1946) is an American cattle rancher from Bunkerville, Nevada who is currently federally incarcerated and awaiting trial with bail denied for his role in the 2014 Bundy standoff.  He vocally advocated a philosophy opposed to what he views as federal government overreach.  He is known for having participated in the 2014 Bundy Standoff in Nevada, an armed standoff with federal and state law enforcement over defaulted grazing fees.  Some viewed him as a hero for having led a movement of ranchers to encourage more ranchers to join him in defaulting on their grazing fees as per their federal grazing contracts.  Some considered him to be dangerously provocative.  He is the father of Ammon Bundy, who in 2016 also led another armed standoff against the government, the occupation of the Malheur National Wildlife Refuge in Oregon.
