The amount the U.S. military spends annually on air conditioning in Iraq and Afghanistan: $20.2 billion.

"When you consider the cost to deliver the fuel to some of the most isolated places in the world -- escorting, command and control, medevac support -- when you throw all that infrastructure in, we're talking over $20 billion," Steven Anderson tells weekends on All Things Considered guest host Rachel Martin. Anderson is a retired brigadier general who served as Gen. David Patreaus' chief logistician in Iraq.
