The Tank heralds the advent of mechanized warfare, and represents in the game, just as in the real world, a game changer on the battlefield. Its mass of armor and cannons is able to crush even modern infantry under its tracks, and its speed remains decent (although less than that of the Cavalry, the Tank is still faster than all other units).
The greatest challenge for the player, however, is to find the resource needed to produce Tanks. The cavalry units of earlier eras (both light and heavy) use basic resources that are revealed practically from the start of the game, but Oil is one of the rarest resources in Civilization VI. Moreover, it is most commonly found off-shore, which requires an even more advanced technology (Plastics) to access. In short, whoever has the Oil has the best chance of reaching a Domination Victory in the Modern Era. If you can't find any Oil, train up some AT Crews to counter the threat the Tank poses.
Like so many efficient ways of killing the enemy in great numbers, the “tank” was first used to any effect during WW1 and perfected during WW2. It is essentially an armored, self-propelled (on caterpillar-type tracks), self-contained fighting vehicle. The concept had been around a long time, and visionaries such as Leonardo da Vinci and Hebert G. Wells had offered simplistic views of an armored leviathan that could dominate a battlefield. But it was the stalemated fronts of WW1, dominated by barbed-wire, machineguns, artillery and mud that brought the concept to fruition. The tank (so-named on the first shipping manifests to mislead enemy intelligence) did not make a good first impression, being used solely as infantry support in the final Allied victory. The defeated learned their lesson, and in WW2 the Germans unveiled the blitzkrieg, the use of massed tanks to blow holes in the enemy lines, then pour through and overrun everything behind. Today, the battle tank is the mainstay of every nation’s army – or at least any big enough to matter.
- The Tank's model is based on the M4A2 Sherman, an American tank that saw heavy use in World War II.
