In about 30 minutes my and DARKKNIGHT5776 are gonna start LASO for halo 4. we would like 2 more people to join us to make this ordeal more manageable. Send me a message on xbox live if your interested: " mangaman0247 "
When doing the ghost run on the 3rd mission, I recommend not having any more than 3 people. You’re probably better off with just 2, unless you’re confident you can all keep pace and form a tight line 
Good luck!
