The starship troopers retrieval ship is an orbit-to-ground carrier designed to retrieve troops and ammo from the battlefield quickly and safely. Large enough to house various vehicles and equipment. Can double as a shuttle for small troop insertions provided there's a safe landing zone since retrieval ships are not heavily armed. The wings retract in order to dock inside Starship hangar bays.
I like the way you used the Mar's sets to make a really cool ship. Not a big fan of the new sets but they ARE better than the ones that they had about 6 years ago. Reminds me of my Pryethium MOC, keep up the good work!
