Where the ability for rapid movement across "tank country" was not possible, armoured penetrations often were avoided or resulted in failure. Terrain would ideally be flat, firm, unobstructed by natural barriers or fortifications, and interspersed with roads and railways. If it were instead hilly, wooded, marshy, or urban, armour would be vulnerable to infantry in close-quarters combat and unable to break out at full speed.
That sucks, i used to think that massing armor and punching through forested areas with lots of infantry would work. One of my critical mistake in Battle of France.
