- "I hereby swear that I will be a proud, brave and vigilant soldier. To uphold the honor of our nation and its military. To submit to the orders of my superiors."
- ― The mantra repeated by SACS pilots
SACS was an Erusean Navy air unit based out of the submarine Alicorn, which saw deployment near the end of Operation Sighthound and during Operation Fisherman. The squadron was based on the submarine itself and launched via an aircraft deck on the top of the submarine's hull. The tail of the SACS aircraft bore a design of an alicorn.
In line with the radical ideology of their captain, Matias Torres, SACS seemed to display a fanatical devotion to their cause. A flight launched purely as a distraction did so willingly and shouted "salvation" just before their aircraft exploded.
At the climax of Operation Sighthound, Torres announced that both he and the Alicorn were no longer under Erusean authority. After launching the submarine and destroying an Osean fleet led by the OFS Puffin, Torres launched a flight from the SACS unit, diverting the attention of Osea's fighter squadrons away from the Alicorn as it submerged. The lead SACS aircraft carried a cruise missile armed with a WMD. Trigger pursued the flight and shot the lead plane down before it could leave the area of operations and carry out the flight's mission.
The remaining aircraft of the squadron would launch days later, when the Osean Navy tried to trap the submarine in the Spring Sea.
