Again, I note that my headline was not intended to indicate that tanks dominated ALL battlefields. I hope you are happier with the last suggestion. But you guys almost make it sound (at least here on the talk page) like it was more a hindrance than an advantage to have tanks! And I remain of the view that it was tanks that reintroduced flanking manoeuvres and deep thrusts into enemy hinterlands, not any other invention or tactical doctrine alone.
