> With all the problems noted over the last few years I'm surprised that anyone wants it
What makes you think anyone wants it?
Buyers of things like this don't buy because they want to, they buy because they're told to.
My friend at DMO (Defense Materials Organization) in Australia spent 2 years of his life on a huge team that recommended the Australian Defense Force don't buy any Abrams tanks for a whole bunch of very valid reasons.
Australia bought a bunch of them anyway, in direct contradiction to the organization who's very purpose it is to make these kinds of purchasing decisions.
