Shortly after Ivan and Gold Team entered the Cosmodrome they were ambushed by a group of Optical Camouflage Soldiers accompanied by two Tactical Engineers. After Ivan and the Devgru Team repelled the attack and fought their way through the Cosmodrome they attacked once again but this time the Optical Camouflage Soldiers were killed by Poison Gas deployed by their own Leader Ludmilla as she tried to kill Ivan and Gold Team with no remorse of sacrificing her own soldiers. Ivan survived however.
