(Help) How To Mod MW3orMW2 Campaign via USB

[Master Chief]

I would like to know how to mod MW3 Campaign with a USB​

Can someone post a LEGIT video on how to do this or telling me on here?​

I'm not new at USB modding I've done it in the past. ​

When I say past I mean way back. I stopped and now I forgot everything about putting game saves into a usb and etc.

So it will be very appreciated if someone did help me find out by posting a video or telling me how. ​
