Halo 5 - All Vehicles and REQ Variants Shown (Halo 5 Vehicle Showcase) 

This video shows every vehicle in Halo 5 as of the Monitor's Bounty Update. I purposely didn't show the skins for the Gungoose because they're the same as the Mongoose skins. Same goes for the Warthogs, which have the same skins as the Scout Warthog. (VEHICLE LIST WITH TIME STAMPS BELOW)
