RTS Wagon Train
The RTS Wagon Train is a Leviathan-class landship from the Henry, Henry, and Paulson shipyards of Carson Colony. The massive modules were built in orbit and put together in Cap City. It is owned and captained by Ebenezer MacDonell, who is almost certainly a legitimate businessman.
It has an ideal crew compliment of 220, is protected by several totally non-military flak cannons, mortar launchers, and point defense emplacements. Its capacious cargo hold also provides hangar space for up to eight Ambulatory Support Platforms as a factory standard, although outsize ASPs can skew that somewhat.
