The ewoks will probably park them on the beach and use them to stop APC landing craft and amphibious tanks.

Can't protect crew served guns from shelling, don't have any sensible coastal defences, don't care about anti air, don't have EW capability to support drone.

So use this thing like a rolling bunker with huge cannon in it, you could destroy a gorrilion landing craft with it, and it's still not really worth hitting with a missile.
