The Pentagon last month created a task force to examine longstanding inefficiencies in U.S. sales of billions of dollars of weaponry to foreign countries, according to the newspaper.

The "tiger team" will look at ways for the Defense Department to streamline parts of the program, the WSJ said, citing a senior defense official.

The aim of the task force is to make coveted American drones, guns, helicopters, tanks and other weaponry available to partners and allies faster, according to WSJ.

The Pentagon did not immediately return a request for comment.
