After two years<ref>{{cite|gfl|sg|Chapter 2-D, Minor Pieces Draw IV}}</ref> without results, the [[KCCO]] and G&K partnered to launch an operation on SF's headquarters and capture Elisa, under the cover of a joint exercise for a PR event.<ref>{{cite|gfl|9-1}}</ref><ref>{{cite|gfl|9-5}}</ref> The true objective of the KCCO was to force Elisa to deploy her [[Parapluie]] virus, then counter-hack her to neutralize and capture her OGAS,<ref name=Sing2A2 /> but it proved to be a formidable opponent in electronic warfare.<ref>{{cite|gfl|sg|2D2}}</ref> Elisa was brought to safety by the traitor T-Doll {{enemy name|M16A1 (Boss)|boss|alt=M16A1}}<ref>{{cite|gfl|sg|End Game}}</ref> while {{enemy name|Agent|boss}} organized the retreat of surviving units, abandoning their home base.<ref>{{cite|gfl|sg|Ranking - Hornet's Nest}}</ref> While working with Sangvis Ferri, M16A1 was not actually under their control and had used her Parapluie infection as an excuse to break from G&K and pursue her own objective<ref>{{cite|gfl|iso|Shark and the Sea VII}}</ref> to prevent {{doll name|M4A1|AR|4}} from merging with Elisa.<ref name=131E /> The SF command was aware of M16A1's status and only trusted her to the extent that she was useful to Elisa.<ref name=Iso46 />

After G&K reinvested Area S09, several operations revealed the presence of Destroyer, Dreamer, Gager, and a remnant body of Ouroboros in the nearby regions, eventually leading to their capture through the services of [[Svarog Heavy Industries]].<ref>{{cite|gfl|dr|Pollinosis VI}}</ref><ref>{{cite|gfl|dr|Ghost Sisters VI}}</ref><ref>{{cite|gfl|dr|Operation Snake Eater V}}</ref> After capture, Sangvis Ferri units were modified with a restriction protocols protocol making them unable to attack G&K units.unit,<ref>{{cite|gfl|[[My Devil's Frontline]]|Crossing of World Lines}}</ref> though cohabitation remains difficult at times.<ref>{{cite|gfl|[[Love Bakery]]|E1, E2}}</ref>

When the Commander requested reinforcements for their operations in Berlin in autumn 2064, Kryuger decided to send the Assimilated forces as reinforcements.<ref>{{cite|gfl|pr|E3-9}}</ref> The ringleaders saved the Commander's force during the battle against Paradeus at the Berlin airport,<ref>{{cite|gfl|pr|E5-7}}</ref> then fought off {{enemy name|Grig|boss}} at the Berlin prison.<ref>{{cite|gfl|pr|E6-7}}</ref> However, their absence left the Area S09 base vulnerable during the [[Fireworks Incident]]. The Assimilated forces participated in [[Operation Aeneas]], represented by Architect and Gager in Squad Ferrum. Ferrum provided heavy cover fire for the other teams and fought against {{enemy name|Narciss|boss}} at the Western tower of [[Avernus]]. They were defeated,<ref>{{cite|gfl|fp|E4-11}}</ref> but collected valuable intel on her weaknesses. More Assimilated forces participated in the subsequent [[Operation Muromets]] under two teams: Team Fe56-C with Judge, Alchemist, Destroyer and Dreamer, in charge of eliminating Narciss, and Team Fe56-D with Intruder and Executioner who destroyed enemy air defenses. Agent also secretly tasked them to recover Architect and Gager's remains and to avenge them.<ref>{{cite|gfl|ss|E3-2}}</ref> Fe56-D completed their mission and assisted the teams in the Eastern Tower,<ref>{{cite|gfl|ss|E3-8}}</ref> but Intruder's aircraft crashed due to heavy radiations.<ref>{{cite|gfl|ss|E3-21}}</ref> After successfully destroying Narciss,<ref>{{cite|gfl|ss|E3-5}}</ref> Fe56-C ran sensitive site exploitation in the Eastern Tower of Avernus, successfully recovering some intelligence despite Paradeus' previous asset denial operation.<ref>{{Incompletecite|reasongfl|ss|E3-21 through 35}}</ref> At this time, at least one ringleader is under the purview of [[Statesec]]: {{enemy name|Beak|boss}}, who also took part in Operation Aeneas as part of Team Black Box along with {{enemy name|M16A1 (Boss)|boss|alt=Add information after Dual RandomnessM16A1}}.<ref>{{cite|gfl|fp|E1-6}}</ref>
