A recent video from FUNKER530 shows POV footage of M1A1 Abrams tanks firing from their main turrets and .50 caliber machine guns - and how the mighty tanks are loaded with their rounds.
A few quick shots inside the belly of the tank shows a loader placing an 'armor-piercing fin-stabilized discarding-sabot' (APFSDS) round inside the main gun.
APFSDS rounds do not carry warheads, instead they are designed to melt through heavy armor plating by traveling nearly 3,500 mph and delivering more than 10,000 tons of deadly force concentrated on an area about the size of a dime.
The animation below shows how the round delivers its hit-to-kill lethality. Once fired, the sabot detaches midair, and the fin-stabilized dart has all the force of a 120 mm round behind it, with a fraction of the air resistance.
The explosion at the end must be from fuel inside the car, as the APFSDS generates extreme, armor-melting heat.
