First Contact - EX / Eclipses & Saros Event / Girlsfrontline

A helpful guide to anyone attempting the stage "First Contact" on hard difficulty for the Eclipses & Saros event in Girlsfrontline.
The event is taken place on June 2023 on the EN server.
Echelons used : 3
Team Comp 1 : AR (x3) / SMG (x2)
Team Comp 2 : AR (x3) / SMG (x2)
Team Comp 3 : HG (x1)
For turn 1 deploy only in the "right carriage"
Deploy your AR / SMG comp to clear the neutral heliport and then deploy your HG dummy and swap the positions so that the AR / SMG is above the dummy HG.
On turn 2 the enemy high threat units will move towards the HG unit and create a gap for the AR / SMG comp to move left and down.
Deploying a SF comp with Scarecrow and using her decoy skill is a suitable alternative instead of a dummy HG if that is easier for you.
Note :
Only deploy your second AR / SMG comp when the heliport in the "left carriage" is about to be captured or you have enough movement points to reach the emp device without getting caught in a battle by the high threat enemy units.
