The mobile gun system isn't exactly easy to ship overseas in a hurry either - unless they've fixed the problem where you have to lift the turret off with a crane before the thing'll fit inside the airplane . . . .

Still, the MGS will probably perform fine in the field - or at any rate it's problems will be more or less manageable. Systems aren't the most important issue here, it's doctrine and soldier training. If the army spent half the money that went into Stryker on counter insurgency training for the current (heavy) force, we'd have gotten a lot father a lot faster in Iraq.

And no, the thing is not a tank. However, it won't be employed that way. Stryker doctrine calls for two mobile gun systems in each company to support infantry operations with direct fire. While the lessons of the Tank Destroyer Corps are important to keep in mind, the Army has (at least doctrinally) produced a micro-scale combined arms force in the Stryker company - direct fire, indirect fire, anti-tank weapons and infantry under a single command which will train together regularly. They should be vastly more effective thank Tank Destroyer battalions.
