Spheroid Dropship:
Walker (time frame)
The Walker quirk reflects that the Dropship can use its landing legs to move one Battletech hex every (time frame). While performing this move, the Dropship cannot perform any loading or unloading of cargo (this includes people walking on and off the Dropship). To reduce this time, take the Dropship's current mass, divide it by the Dropship's max mass, multiply that by the planet's gravity, and multiply that by the time frame.
So a Mule (11,200 tons) that has landing legs capable of performing a Walker (15 minutes) maneuver, has 7000 free tons of space, and is on a planet with 1.1 G. So the Mule Dropship masses 4200 tons (11,200-7000). So 4200/11,200 = 0.375, multiplied by 1.1G = 0.4125 * 15 minutes = 6.1875 minutes to move 1 Battletech hex.
Not tactically useful, but if you need to reposition the Dropships at a Drop port it is useful to be able to move the empty Dropships around. You just can't load cargo to or unload cargo from them while they are walking around. You also want to have local guides for when the drunk crew have come back and are trying to find their Dropship, "Dude, where's my Dropship!".
(Aerodyne Dropships don't need this Quirk as they have wheels)
Dropships (all)
Collar size (tonnage)
Some Dropships have poor integration with their KF antennae and a Jumpship's KF links, forcing the Jumpship to devote more of the field than would be normal for that Dropship's mass. So the Dropship might only mass 20,000 tons, but it needs a Collar with at least 30,000 tons capacity. in the inner Sphere this might not be an issue, but in the Periphery where that Merchant Jumpship has been tooling along for over a century without decent spare parts . . .
Jumpship:
Collar Capacity (tons)
Not all collars can handle a 100 kton Dropship, either due to technology, age, or poor maintenance. This is the actual maximum mass that a specific Docking Collar can handle through a KF jump. Terra-made Jumpships might be able to handle 150,000 tons (so even a 10% loss in capacity is still better than the Inner Sphere), Inner Sphere Jumpships might only be able to handle 120,000 tons, while Periphery Jumpships might have 50,000 tons or less in capacity.
