This is a wonderful question. It's a lot deeper than you would believe. Cars are made better every year. Just about every car in the U.S. had fuel injection by the mid 1980's. When do you think the first fuel injected car rolled off the assembly line?

Would you believe it was 1957?

@shaunwalker7 American tank mechanic here. Some advice.

Tanks are bad at urban combat. They need infantry support. Without boots on ground they're just big targets with poor visibility. Rifles should aim for the periscopes, but most importantly the sight unit on top of the turret. @shaunwalker7 Take down street signs. Don't let the enemy know where they are. Move signs to the wrong streets. Tanks are super heavy, so try to direct them to streets that can't hold their weight. They can't move if they break through to the sewer.
