Cuba is a 1979 movie directed by Richard Lester and starring Sean Connery as British mercenary Major Robert Dapes, an expert in counter-guerrilla warfare, who is hired by Cuban government to organize successful operations against Castro's guerrillas. In Habana, Dapes runs into an old flame, Alexandra Lopez de Pulido (Brooke Adams), who is now married to a wealthy playboy.
Note: the movie was filmed in Spain, which affected the choice of screen guns.
Some government military officers and warrant officers, including a sergeant (Ram John Holder) who leads the patrol unit, carry Astra 400 pistols.
Beretta M1934
One of the rebel workers at the Pulido tobacco factory is seen with a Beretta M1934. The pistol is also seen in hands of midget Jesus (David Rappaport).
Smith & Wesson New Model No.3
After Julio Mederos' (Danny De La Paz) M1911 jams, he takes a Smith & Wesson New Model No.3 from a fellow female guerilla fighter. The revolver is possibly a Spanish manufactured version.
Submachine Guns
Erma EMP
Erma EMP SMGs are used by both government troops and guerillas. They are possibly Spanish manufactured Coruña M41/44 copies in 9x23mm Largo caliber. In one scene, Maj. Dapes (Sean Connery) briefly holds an EMP, taken from a female guerilla fighter.
In one scene, a guerrilla fighter fires a submachine gun that resembles the experimental Vollmer VMP 1928, but it is most likely an EMP with the barrel shroud removed.
Suomi KP/-31
A Suomi KP/-31 with stick magazine is used by numerous guerilla fighters.
Sten Mk II
Both British and Canadian versions of the Sten Mk II SMG are used by guerillas.
Labora Fontbernat M1938 (Modified as Thompson-Style Submachine Guns)
M1928A1/M1A1-Like Version
Guerilla fighters and government troops use submachine guns that resemble both M1928A1 and M1(A1) Thompsons, with "box-shape" sights and barrels of the first, but with a side cocking handle of the second. Their general look allows to guess that they must be modified Labora Fontbernat M1938 SMGs (also, their magazines are of a completely non-standard shape, which suggests that they are also adapted to launch the blank cartritges of unknown type). See the talk page for the discussion of these guns.
M1921/M1928-Like version
Guerilla fighters also carry SMGs that have Thompson-style foregrips, pistol grips, and rear sight guards but differ in having a large space between the trigger guard and magazine well. These guns are also modified М1938 SMGs, but, unlike the first version, they have much fewer changes.
Star Si35
What appears to be a Star Si35 is briefly seen in a guerilla base.
Madsen M50
A Madsen M50 is seen in documentary footage when the victorious Fidel Castro enters Habana.
What appear to be a CETME Rifle of unclear model is seen on a documentary footage that shows a Cadillac Gage Commando armored car.
Machine Guns
Browning M1919A4
Browning M1919A4 machine guns are mounted on jeeps and M10 tank destroyers used by government troops. Larry Gutman (Jack Weston) fires an M1919A4, dismounted from an M10.
Browning wz. 1928
A Browning wz. 1928 is used by a soldier in the opening scene. This Polish light machine gun appeared in Spain during the Spanish Civil War. The screen gun appears to be an early model with removed flash hider.
A pair of 17th century-style Wheellock Muskets are used as decorations in Gen. Bello's apartments. They are most likely non-firing replicas.
Trivia
M10 Tank Destroyer
An M10 Tank Destroyer appears during the battle on gas station. Maj. Dapes captures it from government troops and mans the 75mm gun while Larry Gutman performs the duties of driver.
Fake "Sherman Firefly Tank"
A pair of M4 Shermans participate in the battle at the gas station. They appear to be fibreglass replicas, built on Landrover chassis (originally for A Bridge Too Far).
Cadillac Gage Commando
A Cadillac Gage Commando armored car is seen in documentary footage. It bears Spanish red-yellow-red military insignia and while never used by Cuba, in the movie it is presented as belonging to Gen. Batista's troops.
Mountain Gun
Two cannons are mounted on a railroad flatcar. They appear to be Skoda 75mm mountain guns of WWI pattern.
