Kinect Library help

So after playing through the game with my Kinect sensor and my voice, I’ve gone back to the Library function in the Extras menu but I’ve only managed to get 43/45 items for it. Does anyone know what’s missing from what I have and where I could find it. My list is:

Captain Keyes
Elite Major
Elite Minor
Elite Zealot
Infection Form
Carrier Form
Elite Combat Form
Human Combat Form
Proto-Compound Intelligence (The Proto-Gravemind in “Keyes”)
Guilty Spark
Grunt Major
Grunt Minor
Hunter
Jackal Minor
Jackal Major
Sentinel
Sargent Johnson
Spec Ops Elite
Spec Ops Grunt
Stealth Elite
Banshee
Bumblebee
Covenant Battlecruiser (The “Truth and Reconciliation” itself)
Ghost
Pelican
Scorpion
Shade
Spirit
Warthog
Wraith
Assault Rifle
Frag Grenade
Needler
Pistol
Plasma Grenade
Plasma Pistol
Plasma Rifle
Rocket Launcher
Shotgun
Sniper Rifle
UNSC Marine
UNSC Armored Marine
Activation Index

Quite the list, eh? So, to those who have Kinect and have the full list, what the hell did I not scan?!

Make that 44/45 instead, just found the Cryo-Tube needed to be scanned in!

Longsword is my 45th. i had all those scanned. longsword is the ship MC gets in on the last part of the last level, The Maw. hope that helped!
