There was a ground vehicle only pack? I dont remember there being one but so many things come and go it could be possible.
Did some searching and it did exist! But like most packs, doubt we will see it ever again through RSI.
Depending on how well pirating or boarding ships goes, a couple in an Idris or Kraken could drop a few fireteams with relative ease to take over a capital if done right.
So the Q&A confirms it can only lift up 1SCU containers no higher than off the ground, but doesn't say anything about stacking some up before carrying into a ship. Who is ready to TEST things the TESTie way when cargo refactor comes out?
I messed with it on the PTU and liked it despite not all features currently active, i saw the cargo racks and thought they were for looks, good to know they actually have a purpose!
