"Raven, we'd like your assistance in reestablishing Crest's control over Sector 513. You'll accompany a contingent of our tanks and work with them to eliminate any Mirage forces encountered."

"Mirage is the dominant corporate power in the sector at the moment, but only because they seized control while our attention was focused on other matters."

"Since Crest maintains control of many other sectors in the region, we're interested in reclaiming our hold on 513 so as to preserve an undivided front."

"Given the tight confines in the area of operation, the number of units involved, and the fact that Mirage is using ECM pulses to disrupt radar functions, expect to have your hands full."

"The radar jamming measures that Mirage has employed may make it difficult to discern friend from foe. Choose your targets with care."




Emma: "The green GK model tanks are friendlies."

Emma: "The red BT model tanks are your targets. Destroy them all."

Emma: "All enemy targets destroyed. Mission complete."


Be very careful in this mission, as you can lock-on to literally everything in this mission, and some of them are allies. Only fire at the red-colored tanks and the MTs, don't fire at the green-colored tanks as they are your allies. Do not bother with any radars as the jamming signal is present and will render them useless; you will need to locate your targets visually. Do not fire unless you are sure what are you aiming at - especially since the allied tanks have a camouflage pattern that makes them blend rather well into the environment, so you might not spot them at all at the distance. Do not rely on the FCS too much then and close the distance first to see clearly what is in your sights.

To S-Rank this mission, all allied tanks must survive. To achieve this outcome, you have to be extremely fast. Take a weapon that can destroy the tanks and MTs instantly (such as the KARASAWA) and bring a light AC - you are not going to need much armor, only as much speed as you can muster. There are not many enemies, you just need to dispose of them posthaste so they do not have a chance to kill any of your allies. For that, you only need a single weapon, a true aim, and to stay on the move until every foe is dead. The major intersection is the most troublesome part - past that, the remaining enemies are relatively easy pickings. If you are fast enough, the mission will be over in half a minute.


  • Recapture Sector 513 is the lowest paying mission in Silent Line: Armored Core.
  • If you manage to clear the mission with all the allied tanks surviving, you will get an additional 8000c bonus. You will obtain the left arm weapon MWG-MGL/300.
