I have a question. What terrain vehicle is stored inside the Broadsword? Or does it matter what gets stored there?
Depends on what you mean
There is a basic Air/Raft in a small vertical (folds down and out for launch/retrieval imo) hanger.
And there are typically two ATVs (All Terrain Vehicles) carried in Cutter Modules. The ATVs are big things, 10tons each, and make decent troop carriers. They may be either tracked or wheeled. You could have as many as four ATVs if you swapped out the standard fuel modules.
Optionally you might have AFVs (Armored Fighting Vehicles) instead. These may also be either tracked or wheeled, are the same size (10tons) but are basically light to medium tanks.
Or, another option I've occasionally gone with, is swapping out an ATV or AFV for a Dirtmover. Same size (10tons) and basic shape and capabilities but instead of carrying people or sporting a weapon, it carries dirt and sports a forward bucket. Great for making quick improvised fortifications, landing fields, or demolishing enemy installations in sensitive surroundings (where ortillery would be too messy collateral damage wise

). Or any of a hundred and one other utilitarian needs for Mercs on the ground.
And of course there are also Fighter modules available for the Cutter, but Fighters are not really terrain vehicles.
Hmmm, walkers, combat walkers...
