SOL has two main types of beam weapons: Laser Beams, and Plasma Beams. Plasma beams are heavier and require more crew support, but have a much improved range and accuracy as well as additional range bonuses. Usually Destroyer-class ships and higher can support Plasma beams. GENARI has one main type of beam weapon divided into two subclasses: Laser Beams, and Heavy Laser Beams. Heavy lasers tend to be take up more mass and crew support, but have increased damage potential. Usually Destroyer-class ships and higher can support Plasma beams. Both have same last sentence....Genari don't have plasma beams do they.
