An imperial stardestroyer (vehicle)?
Many told me it can't enter a battlefield cuz it isn't made for entering the atmosphere (though how did the Republic Assault Ships take off in Episode 2 at the end? LOL) but it actually would be absolutely AWESOME
if you could use it as a mobile spawnpoint - attack vehicle like the AT-AT's (with their health & Laser Cannons it would be a great weapon that can stand a LOT of anti-air fire and can only be properly damaged by X-Wing Fighters (their rockets) and Y-Wing Bombers).
