Destroying more than one Voidborn grants more than one Tactics?
Quick answer
Yes, you advance 1 on the Tactics track for each Voidborn ship destroyed. [p.4 — Destroying Voidborn ships]
Details
Whenever you destroy a Voidborn ship, you remove it from the map and advance on the Tactics track by 1 for each destroyed Voidborn ship. [p.4 — Destroying Voidborn ships] So if you destroy 3 Voidborn ships in a single action, you advance 3 steps on the Tactics track.
Additionally, whenever you advance on the Tactics track by destroying Voidborn ships, if your marker passes a Material icon on the track, you gain 1 Material for each icon you pass. [p.4 — Destroying Voidborn ships]
