Blackwater Comparative Costs

So, everyone's talking about how Blackwater costs considerably more per consultant that a regular Army sergeant. But! You can't compare their salaries! The Army has pensions, it trains you, & c.

I haven't seen mentioned in these discussions that, since Blackwater hires exclusively ex-military, we have already paid to train them, and they typically left before they qualified for their pension. We can drop those costs from the analysis.
