To Gap: I thought you asked what the real auxiliary cruisers looked like.
Otherwise in combat, these cruisers actually functioned as Q-ships. Their weapons were masked and unmasked immediately before their own struggle. So, in the case of the Ubi-auxiliary cruisers, side aprons would open and guns would fire.
If I could get the weapons and shells on the auxiliary cruisers working, I think it would be really a masterpiece.
