Military experimentation in the United States 
The United States Marine Corps tested the usefulness of commercial off-the-shelf skateboards during urban combat military exercises in the late 1990s in a program called Urban Warrior '99. Their special purpose was "for maneuvering inside buildings in order to detect tripwires and sniper fire".
