Freedom Ain't free

From Wikipedia, the free encyclopedia

"Freedom ain't free" or "freedom isn't free" is an idiom in the United States that expresses gratitude for the service of members of the military. It implicitly states that the freedoms enjoyed by many citizens in Western democracies are only possible through the voluntary risks taken and sacrifices made by the military.

There are at least three common songs with this title.

The idiom may be used as a rhetorical device.
