"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 supposedly 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

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. Rage noted the presence of "Three Strikes" and the duo prepared to attack. Scream downed an Erusean aircraft, earning the ire of Rage. 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 battle. Scream went on an open channel to warn Trigger that they would meet again and Trigger would die the next time they met.[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, Rage and Scream once again engaged Strider Squadron. Scream damaged Lanza's aircraft 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. Both siblings refused to comply 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. 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.[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 reflective nature of a canopy. This further complicates the ability of hostiles to gauge the aircraft's heading and orientation.
  • It's unusual that Mimic's theme features drums as its lead instrument instead of guitar and/or keyboard. This choice likely intended to portray the eccentric siblings' status as nobodies and/or outcasts despite being aces, and their subsequent thirst for reputation as they said "We tried to be heroes too! We really tried!" during their final dogfight over Anchorhead.
