I like the idea of Transports as units that are A0 D0 M2 C7 units that haul ground units from one shore to another. I also like the idea of groups of transports, that’s 2 or more transports, have a single collective defense roll of 1 on a d6. The transports would be taken as casualties last but so long as there’s 2 or more, they continue to take potshots @ 1 at their tormentors.
And here I thought I was being unique for having thought that up myself, before I read this thread. Parallel Evolution, I guess.
