Insta-jugernog In Tranzit:

This glitch requires you to do a solo match in Tranzit (zombies). Then buy Quick Revive right away. Let the Zombies kill you. Quick Revive will let you be revived. After being revived, let the zombies kill you again. Then when you play Tranzit online with others you will already have Juggernog. This may take a little while to kick in.
