Mitrailleuse
The first "mitrailleuse" was a manually fired 50-barrel volley gun originally developed in Belgium in 1851 by the Belgian Army Captain Fafschamps, who made a rough prototype and drawings of his invention. The system was improved during the 1850s by Louis Christophe and the Belgian engineer Joseph Montigny, with the completion of the 37-barrel Montigny mitrailleuse in 1863. From 1859, Joseph Montigny proposed his design to Napoleon III, which led to the development of the French Reffye mitrailleuse, designed by Jean-Baptiste Verchère de Reffye with the collaboration of Montigny, and which was adopted by the French Army in 1865. Initially kept under wraps as a secret weapon, it was widely used in battle by French artillery during the Franco-Prussian War (1870–71). Smaller numbers of other designs, including the Gatling gun, were also purchased by the French government during the latter part of that conflict. The Reffye model had initially been built in small numbers and in secrecy: only about 200 were available at the beginning of the conflict. This also kept regular French field artillery in a neglected position in the eyes of French emperor Napoleon III, with dire consequences during the Franco-Prussian War of 1870–71.
Mozambique Drill
According to anecdotal history, the technique originated with a Rhodesia soldier, Mike Rousseau, engaged in the Mozambican War of Independence (1964-1974). Fighting at the airport at Lourenço Marques (modern-day Maputo), Rousseau rounded a corner and encountered a FRELIMO guerrilla, armed with an AK-47 assault rifle, at 10 paces (~7.5 meters). Rousseau immediately brought up his Browning HP35 pistol and performed a double tap maneuver, a controlled shooting technique in which the shooter makes two quick shots, to the target's torso. Rousseau hit the target on either side of the sternum, usually enough to incapacitate or kill outright. Seeing that the guerrilla was still advancing, Rousseau attempted a head shot that hit the guerrilla through the base of his neck, severing the spinal cord. Rousseau related the story to an acquaintance, small arms expert Jeff Cooper, founder of the Gunsite Academy shooting school, who incorporated the "Mozambique Drill" into his modern technique shooting method.
