Rather than training soldiers for combat, the Portal beams them in from space. It is a large blue sphere, suspended in the air beneath a structure that resembles a giant, warped football goal. The length of time and cost of teleportation varies between different Scrin units, depending on their complexity - simple groups of Buzzers take almost no time at all, while the Mastermind takes considerably longer. Apparently, Masterminds and Shock Troopers may only be transported down once a Stasis Chamber has been established planetside. From the get-go, however, Scrin Foremen are free to call down Buzzers, Disintegrators and Assimilators as funds permit.
