Listening to this thread has been fascinating. But a good portion of the conversation sounds of a plea to keep the battle tank alive....perhaps past its years.
Suffer that I may even walk in a tank tread's wake, let alone give any statistical meat here. Let me just offer this: can a perceived and legitimate military threat to Canada eliminate a tank force? As far as I have heard elsewhere, the US military (for example) is very proud of its tank-killing capabilities. Perhaps the battle tank is a dinosaur. After all, it makes itself a juicy target just by "being there".
And, what viable attacker would not be of the highly lethal and mobile variety (eg: apaches and quickly deployed ground "fire and forget" infantry)?
Forgive me in advance if I touch nerves akin to the sentiment to perserve the "horse cavalry" of the early twenteth century. But still, I /do/ like the noise that tanks make.
