Dave "Smokejumper" Georgeson has written up a guide detailing some gameplay tips for use with the new vehicle variants. Here's a short clip from the Aurora's gameplay tip:
The Aurora exists to support her troops. Use the Flux Pods while approaching a target to soften up the landing zone. Then offload the troops and fall back to terrain cover with one gunner while covering your other troops' advance, or simply offload and go back for more troops. Repeat as often as liked to ferry groups of troops into harm's way. Although the Aurora is brutal against infantry, and it's weapons are technically potent against armor, the firing arc of the weapon often makes single vehicle-to-vehicle duels a poor choice for the Aurora.
