How does a Tank work (M1A2 Abrams)

Video Summary:
Come see how a tank works! In this video we're going to look specifically at the American M1A2 Abrams tank. The tank weighs 68 US Tons and can go up to 42 miles per hour. Parts of the tank include the caterpillar tracks, the wheels, the hull, and the turret. The caterpillar tracks are used to displace the weight of the tank allowing it cross rough terrain. The tank holds a crew of 4 - the driver, gunner, commander and the loader. The driver is up front and the other 3 are in the turret. The engine is in the back of the tank, it's an AGT-1500 which is powered by jet fuel. The main gun fires shells at about 3500mph. It can hit a target 2 miles away. There are a few countries besides the USA that use variants of the M1 Abrams tank. M1A2 Abrams tank continues to be the main battle tank for the United States military.

I apologize for not including metric units in the video. I normally include both metric and imperial but this video I got lazy. (and yes, even as an American I agree our system is pretty wonky)
I made a mistake with the smoke grenade launchers in the video. They don't emit smoke directly - they shoot out grenades around the tank and then those grenades emit smoke.
For those of you that noticed the anime paint job on the helicopter in War Thunder - yes this is a real thing. Do a google search for "Kisarazu Sisters"
