It's hard to find any simple, clear, current figures, but this has a historical study for deployed units through Iraq 2005 (which clearly isn't exactly what we want), and it shows (in the counts that don't include contractors for Iraq 2005, so the ones that are actually addressing uniformed personnel and using the same standards as earlier figures) the highest tooth to tail ratio since WWII, as part of a late (relative to the whole period of study) reversal of what had for most of the post-WWII period been a trend of decreasing the tooth-to-tail ratio.
