A Standard Body Tank has an effective Strength score of 15. This score is used for everything other than skill total calculations. A recon tank has a score of 14, and Zero-g and Overland models have scores of 16. Many suits of powered armor are outfitted with a jump system, and some are capable of flight. Training is not necessary to activate a jump system, although Acrobatics- flight is necessary to utilize suit flight units.
