Ground & Air Equipment, softback supplement for Space Opera, by Edward E. Simbalist and A. Mark Ratner
“Most players of Space Opera have probably wondered about one of two things; what more can be added to the already extensive lists of equipment? or what happened to Flamers, Scramblers and other heavy weapons? The answer to both of these questions is in Ground & Air Equipment . When Space Opera was completed, it was decided that the heavy military equipment was only of interest to those players with characters in military or mercenary service. For most PCs the heavy equipment under consideration would be outside the realm of their needs or abilities.
But, for those of you with the requirements for use of military equipment, this is it. Tanks and other armored vehicles, combat aircraft and air combat rules, StarFighters, and heavy weaponry with all the additional rules needed to use these additional weapons and weapons systems.”
