If possible, maybe with a future expansion, I think it'd be neat to have ground vehicles. That might drastically improve or expand upon the land combat. You could have large vehicles, where your BOs take various positions on it, or more personal ones. Either way, I think it would be a cool addition.
Unfortunately I'm not too familiar with land based vehicles in the Star Trek universe. Don't know if there would be anything as iconic as say the AT-AT or Landspeeder from Star Wars. But STO could be a great opportunity to add something as far as away team vehicles. Like mechs

Or let's at least have jet packs, that would be awesome.

It sucked.
EDIT: As stated above... Argo was it's name
