Possible Weapons (Not sure of any names):
First of all, these look like covenant weapons but also, notice the resemblance of the P90 from CoD4 some of these weapons have. Also, some resemble the F2000 from Modern Warfare 2 (which means some of these could possibly be re-skinned call of duty weapons) while others have crystal-looking objects under the barrels, possibly bayonettes?
This one is supposed to be the Halo 4 model of the AR. If you look at it you can see there is a scope, which might mean that the AR is returning as a precision rifle. It also has iron sights and what looks to be a flashlight attachment under the barrel and some type of laser pointer on the side. My guess is that if this is the actual AR model for Halo 4, it will not be a fully-automatic weapon.
Possible Marine/Human vehicle:
It's supposed to be called a Sparrow or Sparrowhawk or something of the sort. I'm not too sure if this is a vehicle from Halo: Wars or not because I have seen images of it on google inside of frames with Halo: Wars on the bottom. Anyways, it looks like a human variation of the banshee mixed with the hornet. It has 1 chain gun turret on both sides that look like they would either be controlled by passengers OR controlled via toggling weapons via the Y button to switch between the side turrets and the front turret (similar to the banshee's system of switching between the plasma cannon and regular plasma turret.)
