The Leopard is an extremely small and cramped DropShip belonging to the Marauders. It's your only means of transportation until you acquire the Argo. It also cannot be upgraded at all, unlike the Argo.
Staffed by XO Oliveira, the command center contains the contracts interface, allowing you to browse and accept contracts.
The barracks on the Leopard are represented by a screen next to XO Oliveira. You can improve your pilots' skills (unlocking new abilities), dismiss them, and hire new pilots here. The Leopard is limited to just eight bunks for MechWarriors, though.
The mech bays are where the magic happens. Overseen by Chief Mech Tech Virtanen, the bays can store only six Mechs and cannot be upgraded (hey, it's a small dropship).
