Pause at 1:12 I already see two major errors.
1. Samuel can be seen wearing CQB. The CQB armor variant was not developed until after the Battle of Jericho VII which took place in 2535. Thats 10 years after this scene.
2. Samuel is also seen wielding a Battle Rifle. Not only was the BR we know today not developed yet(Outside of a few prototypes such as the XBR-55, but why would the Spartans have access to that?) but the BR he is holding is the BR-85, a weapon that was not developed until late in the Covenant War almost 30 years later and based on the data from the BR-55 and BR-55HB which didn't even exist yet.
3. We also see later in the trailer a brief flash of Linda in ARGUS-class Mjolnir, which to my knowledge didn't exist yet either.
