Shipping costs could be a problem
Odds are it'd cost about as much to ship a T-34 from Russia as it would to buy one. Still, that's about half the price of a Hummer. As for equipping the Iraqi army, T-34s would make for good target practice but in today's world, they wouldn't stand a chance against a modern MBT. But they'd kick the crap out of a Hummer. Rough on the roads, though.
Of course, as an airplane lover, this is what I'd really like to buy from Russia. Yowsa! More expensive to buy but cheaper to operate than a Mig.
