U.S. Special Operations forces (SOF) deployed to 133 countries -- roughly 70% of the nations on the planet

"During the fiscal year that ended on September 30, 2014, U.S. Special Operations forces (SOF) deployed to 133 countries -- roughly 70% of the nations on the planet -- according to Lieutenant Colonel Robert Bockholt, a public affairs officer with U.S. Special Operations Command (SOCOM).  This capped a three-year span in which the country’s most elite forces were active in more than 150 different countries around the world, conducting missions ranging from kill/capture night raids to training exercises."
