Think of it, from an orbiting fleet or from L-5 colonies anything from a platoon with a single dropship or 200 dropships for a full marine division landing anywhere on planet in 10 minutes or less. Differing compliments such as 4 fighting vehicles and crews, main battle tank and troopers, a field hospital, a tanker of fuel, or submersibles and fast boats - any force for any mission required. This is the workhorse of the colonial marines.
