The 10th Cavalry Brigade (Polish: "10.
 Brygada Kawalerii" ) was a Polish military unit in World War II.
 It was the only fully operational Polish motorized infantry unit during the Invasion of Poland, as Warsaw Armoured Motorized Brigade was not completed by September 1, 1939.
 Commanded by Colonel, later General Stanisław Maczek, it is considered one of few Polish World War II military units (brigade size or larger) not to have been decisively defeated in 1939 .
 Another was General Franciszek Kleeberg's Independent Operational Group Polesie ( a corps or field army).
General George Smith Patton Jr. (November 11, 1885 – December 21, 1945) was a senior officer of the United States Army who commanded the U.S. Seventh Army in the Mediterranean and European theaters of World War II, but is best known for his leadership of the U.S. Third Army in France and Germany following the Allied invasion of Normandy in June 1944.
The First Motion Picture Unit (FMPU), later 18th Army Air Forces Base Unit, was the primary film production unit of the US Army Air Forces (USAAF) during World War II and was the first military unit made up entirely of professionals from the film industry.
 It produced more than 400 propaganda and training films, which were notable for being informative as well as entertaining.
 Films for which the unit is known include "Resisting Enemy Interrogation", "" and "The Last Bomb"—all of which were released in theatres.
 Veteran actors such as Clark Gable, William Holden, Clayton Moore, and future President Ronald Reagan and directors such as John Sturges served with the FMPU.
 The unit also produced training films and trained combat cameramen.
 FMPU personnel served with distinction during World War II.
The 18th (Croatian) Eastern Bosnian Brigade was a World War II military unit of the Yugoslav Partisans.
 It was formed in October 1943 in the Husino village (in today's Bosnia and Herzegovina) after the capitulation of Italy forced the Germans to move a large part of their forces to the Adriatic coast (in order to disarm the Italian army before the Partisans did).
 The formation of the unit allowed the Partisans to liberate the lightly guarded city of Tuzla and hold it for 40 days, before the Germans retook it in Operation Ferkel.
The 658th Eastern Battalion (German: "Ost Bataillon 658" ) was an Eastern Front World War II military unit of the Wehrmacht composed of Estonians.
 It was formed on 23 October 1942 from "Estnische Sicherungs-Abteilung 181" by the German 18th Army and fought in Northern Russia.
 In June 1944 it was dissolved and its personnel used to form the "47th Waffen-Grenadier Regiment 2nd Battalion" of the 20th Waffen Grenadier Division of the SS (1st Estonian).
The Lim-Sandžak Chetnik Detachment (Serbian: Лимско—Санџачки Четнички Одред ) was a military unit of Chetniks that was established in northern Montenegro and Sandžak at the end of June 1942, during World War II.
 In August 1942, it was commanded by Pavle Đurišić, and was the largest and the most elite military unit of Draža Mihailović at that time.
The 1908 Pattern Cavalry Trooper's Sword (and the 1912 Pattern, the equivalent for officers) was the last service sword issued to the cavalry of the British Army.
 It has been called the most effective cavalry sword ever designed, although ironically its introduction occurred as swords finally became obsolete as military weapons.
 In use, it, like other thrust-based cavalry swords, is best described as a one-handed lance, due to its complete lack of utility for anything but the charge.
 In fact, the closely related US Model 1913 Cavalry Saber was issued with only a saddle scabbard, as it was not considered to be of much use to a dismounted cavalryman.
 Colonial troops, who could expect to engage in melee combat with opposing cavalry frequently carried cut and thrust swords either instead of, or in addition to the P1908/1912.
The Model 1913 Cavalry Saber, commonly referred to as the Patton Saber, was a cavalry saber designed for the U.S. Army by Second Lieutenant (later General) George S. Patton in 1913.
 Patton suggested the revision from a curved sword and edge and cutting technique to a thrusting style of attack, following his extensive training in France.
The 5th Krajina (Kozara) Assault Brigade was a World War II military unit of the Yugoslav Partisans.
 It was formed on September 22, 1942, at Palež on the Kozara mountain out of the 2nd 'Mladen Stojanović' Partisan Detachment.
 On the day of the brigade was formed it had around 1,100 soldiers armed with 940 rifles and 45 light machine-guns.
