You can get any mode that is in normal private match . In combat training. This doesn't work with modified game modes (fast run speed etc...) and no you can't get banned for this! I've been doing it for a while now and not been banned

So Say for example you wanted search and destroy you would get 500xp per kill and it sticks. It's fun to play around with

So post down below your gamertag and what game mode you would like and I'll invite you to my game ASAP my NAT is moderate so I hope you can join sorry if you can't

game modes you can have are:...
Search and destroy
Domination
Headquarters
Demolition
Capture the flag
Sabotage
