Here are some vehicles I feel should make a comeback/appearance!
- Brute Choppah(If not for campaign, then for multiplayer)
Hornet
Specter/prowler
Booster Frame ( if you don’t know, its in the store under avatar gear, and its what the spartans drove in Halo Legends in the package.
ELEPHANT
-Also, put in pelican for multiplayer 
The Revenant is the best thing Reach came up with. Love that vehicle. If one Halo game has both the Chopper and the Revenant in it, my gaming life is complete.
We need an entire arsenal of aerial vehicles for BTB in both UNSC and whatever else variants, not just a couple. Light attack, light transport, heavy transport, heavy attack, total airship.
Also, the Elephant.
I’m gonna save time writing them out by saying everything but the revenent and falcon.
Here is a list of every vehicle I want to return:
Warthogs
-Warthog
-Rocket hog
-Transport hog (Players can go in back seats.)
-Gauss hog
Light vehicles
-Mongoose
-Ghost
Stationary
-Machine gun (portable)
-Gauss turret
-Plasma turret (portable)
-Shade turret
Heavy vehicles
-Wraith
-Scorpion
-Cyclops
-Elephant (has canopy)
-Elephant (has no canopy)
-War sphinx (would this work?)
Middle-class vehicles
-Cobra
-Spectre
-Chopper
-Revenant
Aerial
-Darter
-Banshee (cannot use banshee bombs)
-Falcon
-Transport Falcon
-Heavy banshee (can use banshee bombs)
Miscellaneous
-Moa
-Civilian vehicles
-Forklift
-ODST drop pod (in invasion, Spartans spawn with these and drop into the battlefield.
Example.)
Let me know if I missed anything.

Now this may sound like an odd request, but I’m going to have to ask you to jump out a tenth-story window.

OK, but if it’s alright with you, I’ll bring a parachute.
I don’t have anything against the revenent. I’m just indifferent as to whether it’s in or out.

That means we need huge maps. I don’t want to drive a cruiser/ Frigate of any sort. But having them send in reinforcement for an invasion type game would be cool.
A map where the Elephants are more important than they were on Sandtrap. I mean where the Elephants is in the focus, and the whole map is built for an Elephant war.
I agree with your vehicles OP and to add to them:
-Elephant
-Banshee
-Ghost
-Pelican
I assume most of the UNSC vehicles from past Halo games will return and all have a new look with better technology and equipment with more time for research after the war.
