Your right Dis, it's 12 per Squad. 4 squads per platoon and an unlimited amount of members to an outfit. Using the various levels of organization, including unlockable command channels, selectable way point and objective mechanics (once those certs are implemented) the size of your combat force is merely limited by the numbers of personnel you have. As for transports, both the Sunderer and the Galaxy have the ability to load a default of ten personnel, two of which can be MAX suits. This capacity can be increased to twelve on both transports via certifications (unlocked by default in the beta).
