You already have a post about this in the support forums, no need to create multiple topics. If you suspect players of cheating then you can report their gamertags to Xbox Live using the built in tools on Xbox. If you have any clips of this, you can file a report on the Halo Support site and include the relevant information.
It’s worth noting though that it’s not currently possible to mod the Xbox One or any of its games, so the kind of cheating you are describing is highly unlikely. It’s more likely that’s it’s a server issue or something related to your connection. Lag can make it appear as if players are shooting you through walls.
