10th Motorized Cavalry Brigade (Poland): 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).

Patton: 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.

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.

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.

658th Eastern Battalion: The 658th Eastern Battalion (German: "Ost Bataillon 658" ) was an Eastern Front World War II military unit of the Wehrmacht composed of Estonians.

Pattern 1908 and 1912 cavalry swords: 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.

Model 1913 Cavalry Saber: 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.
