18, according to what appears to be a military incident report shared on Instagram and Reddit. The bizarre assault took place at Inyokern Airport, an airfield in the Mojave Desert about 100 miles north of Los Angeles, sometime after 1 a.m. A sword-wielding man dressed as a ninja attacked several special operations soldiers who were training at a California airport, reportedly forcing them to shelter in a hangar and inflicting wounds that required stitches.
