"When the Covenant had me locked up, I heard some information about this ring world, they call it: Halo. I heard that the covenant said it was a weapon of mass destruction that could spread upon the whole universe, wiping out any life. If this is true, we can't let the covenant use it against us, or the human race will be no more. I am going to give you a misson chief:I want you to destroy any covenant thats dum enough to get in between you and finding out Halos true purpose. I'll help as much as I can. I'm going to send you as much UNSC soldiers as I possibly can. Seargent Johnson and his men shall help you as much as they possibly can. Captain Carol Rawly aka Foehammer aka Echo 419 shall help you by dropping in the marines and vehicles such as warthogs and scorpions that you shall need in your battle. You shall not be helped by the other spartons because they're all missing in action. here is a list that shall tell you which spartons are still alive:Li-008 (MIA), Vinh-029 (MIA), Joshua-030 (MIA), Sam-034 (MIA), Isaac-039 (MIA), William-043 (Active), Anton-044 (MIA), Linda-058 (Active), Malcolm-059 (MIA), Fhajad-084 (WIA), Kelly-087 (MIA), Grace-093 (MIA), Frederic-104 (Active), John-117 (Active), James (MIA), Kirk (WIA), Rene (WIA), Cassandra (MIA) The MIA stands for missing in action. You shall have the same fate if you do not help in defeating the covenant. Only you can decide whether you want to help or kill. Its your choice chief. Smoke Dogg, head of the UNSC forces out."
