Let's just remember the nature of the threat. We are no longer going to be committed into action against the Russian hordes or against a tank based army on an open front. As the theorists are fond of saying the world is becoming more urban, thus more battle will be fought in the urban environment. The American experience so far with the SBCT in Iraq has so far, proven that the Styrker with Slat armour can defeat both RPG and IED attack. Yes I would prefer to have the Abrams underneath me and yes I love the rumble of the Leopard when it starts up. But part of the fear inspired by the tank rumble also warns the enemy that we are coming, especially when magnified in the urban environment. The Stryker apparently puts fear in the enemy now because it can litterally sneak up on you. Keep in mind that in the urban environment tanks should never work alone and this will be true for the MGS. I agree that the MGS may not be ideal but it does offer advantages. The government has made a commitment or policy as to what type of operation we are to be involved with in the future, whether this is based on understanding of our capabilities or sound advice from the leaders, is up for debate. The MGS is not being used by the Americans to replace tanks like we are, but Canada is not alone in adopting a primarily wheeled fleet, even the Brits are re-rolling a large chunk of their Armoured units. For the type of operations we will face in the future the MGS is sufficient for our needs. :-\
