Battlefield 2142 Northen Strike Maps Confirmation

Hello. 

A few days ago I finally did what I wanted to do a long time ago and I purchased BF2 Complete Collection and BF2142 Delux Edition. in the game's description was written that it's include with BF2142 Northen Strike but when I went in-game I found out that some maps were missing from the SP menu. 

Are those maps are MP only or there its something else?
