In a minute-long video posted to the Department of Defense’s Facebook page on May 20, Marine Corps drill instructors mercilessly taunt, scream at, and correct recruits at Marine Corps Recruit Depot San Diego, California. The video appears to show a platoon of recruits during initial drill, which is meant to test the bearing and knowledge of would-be Marines. Initial drill, like much of the first four weeks at boot camp, is a ragefest where drill instructors get to fly off the handle and have fun dousing recruits with spittle and insults. Good times.
