Signature: Dust Curtain. The dust wall leaves a broad lane. Expect it to switch sides next time. This is fictional battle design, not a claim about the real subject.

How this card plays
Staggered rows enter at different heights and alternate their shots. Change horizontal lanes before the next row reaches the ship. The first warning introduces Dust Curtain. Later volleys alternate between that signature and the formation pattern. Survive three waves to earn a clean clear, or take one free assisted clear.
