|Briefing|| Commander, the Black Legion is attacking a detachment of Blood Ravens scouts.
Sergeant Priam led a group of initiates to investigate an intermittent positioning signal emanating from the depths of the Calderis desert. They expected to recover the remains of brothers lost during the Tyranid war. They found the Black Legion laying in wait. We cannot allow the Chaos Legions to destroy them. "Play the distress call."

Full walkthrough not complete.
Move quickly to save the first set of Scouts, immediately west of the start point. They are under attack as soon as the mission begins.
After this, make your way to the Chaos Portal in the southwest corner of the map, and destroy it. Taking time to do this is safe, because the other Scouts will not come under attack until you approach.
For that reason, it is usually not a good idea to explore with Cyrus ahead of the rest of your forces, because even approaching under Infiltrate will trigger the enemies to start attacking Scouts. Instead, approach the objectives in force with all your squads at once. Disrupt the enemy as much as possible and use Tarkus's Taunt to draw attention. Use explosives cautiously or not at all, due to the risk of destroying buildings and killing the Scouts within.
