Using the new cards from the Imperial Veterans article, this seems like a pretty scary list:

Gamma Squadron Veteran + Homing Missiles + Long Range Scanners + Crack Shot (25)

They can pick up target locks well before engaging due to Long Range Scanners, and then each can make a TL + focus four dice attack, ignoring evade tokens and adding Crack Shot. That's likely to one-shot a TIE or Z, and two of them can probably take down a Y or B. Even aces and tough targets like Aggressors will get hit pretty hard.

They don't have much left after taking their shots -- just four clumsy TIEs with some extra hull -- but that opening salvo looks like it could wipe out half or more of a lot of lists.

That is the coolest alpha strike I can imagine, but I wish you could include EM there. Maybe by removing one Bomber for something cheaper...

Also gains a bit of controll by including a Conner Net. Such a great expansion, I am so stocked!
