Tank guns have evolved from crude WWI cannons into high-pressure smoothbores firing fin-stabilized darts, guided missiles, and programmable ammunition.

This video explains the major types of tank guns and how each one actually works, from early low-velocity support guns and 20mm autocannons to the 75mm and 88mm weapons of World War II, Britain's 105mm and 120mm rifled guns, Soviet 115mm and 125mm smoothbores, NATO 120mm guns, and experimental 130–140mm systems.

Along the way, we break down famous weapons and vehicles including the Mark I, Renault FT, Panzer II, Panzer III, Panzer IV, T-34, Panther, Tiger, Sherman Firefly, IS-2, FV4005, Centurion, Challenger 2, Sheridan, T-62, T-72, Abrams, Leopard 2 and Challenger 3.

You'll also see why caliber alone does not determine firepower, how APDS and APFSDS work, why smoothbore guns became dominant, what separates HEAT from HESH, how gun-launched missiles work, and why some tanks use human loaders while others rely on autoloaders.

Which tank gun design do you think achieved the best balance of firepower, ammunition capacity and practicality?
