Special Warfare Group Nine

was a UNSC Special Forces Group corresponding to the SPARTAN-III program. The unit was mostly devised as a large scale raiding force, specialising in commando raids on vital enemy positions. SWG 9 was probably one of the most secretive Spartan units, outside of Holland's SWG3. The unit had massive attrition rates and by the end of the war, near collapsed, with the CO and founder, Colonel Ackerson being killed in action in the Sol System and the last surviving company, Gamma, being redeployed to SWG 7 and 3.
