Lyrics
A main battle tank today faces many threats that can kill it - direct fire from other tanks, guided weapons launched by infantry and from helicopters, cannons shot by aircraft, artillery fire, mines. To survive, it needs armor, and lots of it. But armor whether conventional rolled or cast nickel-chrome-molybdenum steel or the modern composite called Chobham (based on a British concept) is extremely heavy. A tank clad top to bottom with armor thick enough to counter every threat would be too weighty to move. No road or bridge could support it, and it would be nearly impossible to transport, especially by air. Consequently, tank designers are forced to compromise. Swapping invincibility for mobility, they mount the thickest, heaviest armor in front, where the danger is the greatest, and provide thinner lighter shields elsewhere. To disable a tank, an antitank round does more than merely pierce the armor that protects the vehicle, it wreaks havoc inside as well. One simple way to accomplish this is to hurl a metal shot against the armor. If the projectile is dense enough and its speed is high enough, it will posses sufficient kinetic energy to penetrate the armor, bringing with it fiery fragments that bounce around the interior, destroying equipment, igniting stored fuel and ammunition and endangering the crew. Hurray.
