or maybe your opponent chooses the card for you? Lando does double dip on the conflict after all.

When you really think about it, this "is" their Tank. Despite what the movies show you, the vast majority of Rebels were just regular people pushed far enough by the system to grab whatever was to hand and try to give the Empire a bloody nose. They are the poster child of "Insurgents with Good Intentions" and what do insurgents use as Armoured Support but Pickup Trucks and Vans with guns strapped to them? The Landspeeder is a Technical and this would be a "Heavy Technical".

So, technically those numbers are Legends. Size wise, since it's first canon appearance is in SW:Commander that game should be used to set it's canon scale. In that game, it's the same size as the Imperial Troop Transport, and both are far smaller than the AT-AT. Since we know the size of the ITT from it's Rebels and Mandalorian appearances, it's safe to assume the A-A5 will be scaled to those measurements. Definitely Occupier Base for both tho, assuming the ITT is the Imp counterpart.

Here's an Idea: Shen Tie Bomber When you would be destroyed for the first time, instead discard half your received damage cards.
