"They're neither Osean nor Erusean. They're just filthy bats!"

Mimic Squadron was a mysterious mercenary and assassin unit belonging to GR Guardian Mercenaries. They briefly appeared in the first two DLC missions for Ace Combat 7: Skies Unknown. Despite bearing Osean emblems, the squadron was hostile towards both Osean and Erusean forces.[1] They were hired by former Osean Brigadier General Howard Clemens, to assassinate Trigger.[2]

The squadron was comprised of the van Dalsen siblings: Otto, callsign "Rage"; and Elke, callsign "Scream". Upon the deaths of both siblings, the squadron is believed to no longer exist.[2]


Sometime before September 4, 2019, Osean Brigadier General Howard Clemens supposedly contracted the siblings to assassinate Trigger.[2]

Mimic Facing Off Against Trigger

A damaged Mimic aircraft dogfighting against Trigger

During Operation Sighthound on September 4, 2019, as the LRSSG's Strider Squadron cleaned up Erusean aircraft threatening their landing fleet, Mimic Squadron appeared on radar posing as Osean forces. They used Osea's radio frequencies but did not show proper IFF. This, along with the fact that there were no more scheduled reinforcements, lead AWACS Long Caster and Wiseman to identify them as hostile. As the siblings entered the battle, Elke downed an Erusean aircraft, earning the ire of Otto. The siblings bickered before engaging Trigger in a heated dogfight, using their modified aircrafts' ECM capabilities to create fake targeting boxes and to break their opponents' lock. Ultimately, the siblings were forced to retreat from the airspace. As they fled, Elke went on an open channel to warn Trigger that they would meet again and that the Osean ace would die the next time they met. The Strider Squadron pilots quickly dubbed them 'the bats'.[1]

Operation Domino

"To unidentified aircraft! Cease combat immediately and withdraw!"

Six days later, during Operation Domino on September 10, 2019, Mimic appeared at Anchorhead just as the LRSSG's operation was ending. Armed with stronger ECM and new stealth missiles that didn't trigger missile alerts, Otto and Elke once again engaged Strider Squadron. Elke damaged Lanza's aircraft in a surprise attack with a stealth missile, forcing him to retreat. Mimic then engaged the remaining two Strider pilots, Count and Trigger. During the dogfight, their benefactor, Brigadier General Clemens, contacted them and ordered them to withdraw from the airspace, with the Osean top brass having determined that Trigger was necessary to win the war. Both siblings refused to comply on the basis that their reputation would be damaged if they returned without eliminating their target and continued to engage Trigger and Count. Despite their technological advantages, Count switched to a secure line to communicate a plan to Trigger - he would draw their attention while Trigger dealt the death blow to the bats. Count was able to lure the two apart long enough for Trigger to shoot them both down without them coming to each other's aid. Both pilots refused to eject and died when their aircraft exploded. Their benefactor, Clemens, was later arrested for treason.[2]



  • Mimic's livery appears to reference dazzle camouflage, a World War I-era camouflage for naval vessels intended to make it difficult for hostiles to gauge the ships' distance, speed, and heading. They also feature false canopies in the form of reflective paint on their front landing gear door to emulate the nature of a glass canopy.
  • Each portrait on the `Ace Combat 7` Japanese website's filename is formatted as [Faction]_[Number]_small.jpg. For example, David North is oia_01_small.jpg, being the first portrait from the OIA. Despite being portrayed as part of a separate faction on that page, Mimic's portraits are interestingly called ahrico_02_small.jpg and ahrico_03_small.jpg, with "ahrico" being the phonetic English translation of "Alicorn" in Japanese. With ahrico_01_small.jpg being Matias Torres, it's unknown if Mimic was originally intended to be allied with the Alicorn in any way, but the connection was never made in the final game, and Mimic is instead allied with GR Guardian Mercenaries.
  • The theme "Mimic", played during the fight with the squadron during Anchorhead Raid, is comprised of four separate music tracks - 3 drumlines and a guitar and keyboard section. At the beginning, the "default" drumline plays along with the guitar and keyboard. Depending on which sibling is killed first, the music will switch to match the situation.
    • If Rage is shot down first, the drums lose their organized rhythm and devolve into mindless percussion (transitioning into the "Scream Drumline"), representing Scream's mental state completely falling apart after her brother's death.
    • If Scream is shot down first, the drums begin to play faster and frantically as the guitar grows even louder, (transitioning into the "Rage Drumline"), representing Rage's cold and calculating demeanor being replaced with blind fury over his sister's death.
