I'm going to have to disagree with this. First and most importantly infantry must be carried in a bay, there's ways around this, but they both mean you have to devote more tonnage to transporting the the infantry.
Right on to vehicles then. There's no reason NOT to transport 50 and 100 ton vehicles by bay and once you account for crews and maintenance staff a very good reason to do so that might also apply to vehicles 5 tons lighter then that.
I think your missing my point SCC.
The issue is military droppers are not very large & we are talking about moving a big force in a limited # of DS/JS.
A single Mule is larger than 90% of the Military ships out there & it devotes less space than most of them to Engines, Armor, & Weapons. Which means it has LOTS of space in bulk cargo.
Just 1 of its 3 cargo decks can hold over 2 battalions of Infantry in Steerage class quarters that have good Food Consumption rates.
The same space using Infantry Bays could hold 20 Regiments (w/o the food they would need)
Either way that is more than a condor & its just 1 of 3 cargo bays.
2 Companies of 100 Ton tanks (4 of 50 tonners) can fit in another bay with plenty of space left over for their crews & the extra food needed.
But none of this food will really be huge amounts because I wasn't suggesting moving to & from Sian to Strana Mechty in bulk cargo.
I was saying you can use that method to make a single jump across the boarder to attack from Thorin to Dieron.
Yes, Military
Bays are more efficient for sure, but Military
Dropships are not.
So you move a big enough force to secure a port via combat drop & 1st wave & then the 2nd wave offloads from bulk haulers.
