Haven't seen any info about the ramming rules for Huge ships. Are they the same as for other ships? (I would think a ssd would crush a small ship completely, what with it's huge size, just like xwing epic scale)
If not, it seems an easy method like Rieekan and plonking 1 cr90 or other cheap ship in the front of the ssd every round during engagement would keep it stuck in place and allow the rest of the Rieekan fleet to flank and break the ssd.
