This promotional film (circa 1960s) for the Bofors 20 mm L/70 automatic gun introduces a tracked armored carrier that significantly enhances the efficiency of armored infantry by offering versatile combat support roles, including troop transport, medical evacuation, and use as a command vehicle. A key feature showcased is a newly developed 20 mm turret gun mounted in a 15 mm armored dome, designed with comprehensive protection, gas-tight sealing, and all-round visibility for the gunner. The turret allows for both ground and anti-aircraft engagement, with effective fire against light armored vehicles, machine gun positions, and helicopters. It includes advanced aiming mechanisms with fine and coarse traversing gears, electromechanical firing controls, and a magazine system holding 80 rounds. Two ammunition types are featured: high-explosive and armor-piercing, both with high muzzle velocity and reliable dispersion performance. Weighing 700 kg, the dome can be mounted on various platforms, including patrol vessels, tanks, and armored cars. Built for rugged use, it withstands heavy firing while ensuring protection for the gunner and weapon, meeting both current tactical demands and future combat expectations. (Note: The weapon shown is a distant relative of the famous Bofors 40 mm L/60 anti air gun, aka the "Bofors gun". The 40 mm L/60 is an anti-aircraft/multi-purpose autocannon designed in the 1930s and was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well as by the Axis powers.) 0:00 – Titles 0:38 – Introduction to the tracked armored carrier, highlighting its role in transporting troops, wounded personnel, and materials in combat zones. 1:08 – The carrier is praised for improving armored infantry efficiency. 1:34 – Introduction of a new 20 mm turret gun designed for armored combat vehicles. 1:48 – Description of the standard armored dome: 15 mm armor plate, bulletproof observation prisms, and a two-position exit cover for protection and anti-aircraft use. 2:22 – The turret gun is meant for anti-aircraft use against slow-moving targets like helicopters and gliders. 2:46 – A periscope sight is used for ground targets, with night-time illumination and aiming tools. 3:08 – The gunner uses traversing and elevation cranks with two gear ratios for fine and coarse aiming. 3:48 – Elevation range is +48° to -15°; the firing gear is electromechanical with single or automatic fire options. 4:13 – The weapon is simple, sturdy, and has also been tested for fighter aircraft use, with a firing rate of approximately 12 rounds per second. 4:37 – Gun protection includes 10–15 mm armored plates and a blocking device to stop firing when the magazine is empty. 5:06 – The magazine holds 80 rounds and is easily reloadable. 5:30 – Two types of ammunition are available: high explosive shell and armor-piercing rounds, both with high muzzle velocities around 850 m/s. 6:14 – Dispersion test shows 50% of a 10-round series within a 6-meter radius. 6:38 – Practical test results: a hit on a light armored vehicle at 1,200 meters in 6 seconds using 3 rounds; a 50% effect against machine guns and close-range anti-tank weapons at 800 meters in 10 seconds using 5 rounds; and a hit on a helicopter at 1,000 meters in 8 seconds using 20 rounds. 7:33 – The dome weighs 700 kg and is suitable for patrol boats, tanks, and armored cars. 7:56 – It's a versatile and rugged solution to modern armament needs. 8:18 – Operated by one man, the dome is gas-tight, offers 360° visibility, and safely vents gases. 8:35 – Reconnaissance via binoculars is possible inside the dome; it’s effective for anti-aircraft firing and protects both gunner and weapon. 9:00 – Final remarks note that it is designed with tactical and technical requirements in mind for present and future combat scenarios. 9:19 – The film concludes with music and branding as a Bofors product for efficient defense.
