There are many, because everyone who pre-ordered got one (well, most everyone), and if you didn't get a code, you can't play as Johnson.
You should get it with Halo 3 ODST on a token. Its the sort of same thing you do to redeem Microsoft Points.
no only if you preorder
You had to Pre order it to get Johnson.

You need to preorder Halo 3 ODST and have the code on XBOX Live to get Sgt. Johnson
