A Top Secret Army Military Occupational Specialty Code also known as The Army Combat Ninja. Like most ninjas, a 99 Zulu is considered one of the most bad ass people on the planet. In addition to normal ninja skills, (Silent, invisible, and extremely deadly) Zulus are very proficient in the "knife hand" known only to the trade. Some 99 Zulus have been rumored to meet at a place known only as H Squared. It should be understood that if you ever encounter one, you should lay down, curl into the fetal position, and wait for a quick, clean, and very silent death.
Chuck Norris met a 99 Zulu one time. Thats why you dont see him on TV anymore.
