The Sickener

The Sickener was a training facility used by the Galactic Republic's Grand Army on the extra-galactic planet Kamino that was used in clone commando training by 22 BBY. The Sickener earned its name by requiring aspiring commandos to crawl, wade, or slither through a huge field of trenches filled with the rotting entrails of animals such as nerfs and other decaying matter in order to prepare for combat scenarios. The cloned soldiers were reminded by their instructors that the course was nothing compared to the horrors of actual warfare. To prove he would not order his commandos—including the men of Omega Squad—to endure any hardship he himself was incapable of, Sergeant Kal Skirata of the Cuy'val Dar endured The Sickener, the seasoned Mandalorian vomiting in the process before his troops, thereby earning their trust and respect.
