The correct answer is "Government leaders have limited powers."
The feature that is a characteristic of a democracy is "Government leaders have limited powers."

This MARSOC element trains, advises, and assists friendly host nation forces, including naval and maritime military and paramilitary forces, to enable them to support their governments' internal security and stability, to counter-subversion, and to reduce the risk of violence from internal and external threats.
