Starting small huh? I assume you mean drivable so... Warthog Scorpion tank Ghost Banshee Shade (If that counts) ...I believe that's it. Unless Wraiths were drivable and I forgot them. If your talking non drivable, there would also be Spirits Pelicans The [i]Truth and Reconciliation [/i] which I believe was a Covenant Capital ship. A Halcyon Class Cruiser ([i]Pillar of Autumn[/i]) A single Lonsword interceptor And the [i]Pillar of Autumn's[/i] escape pods.
