Walk it off
At first you'll realize that the assault rifle Johnson gave you isn't in your hands. Don't panic, it'll appear in your hands once you went near to the arbiter. Then 1st time players will want to test their Spartan powers first by overtaking the marines and realizing you can easily jump to platforms while they have to climb. You will also get an objective: Get to the River for evac. Where's the river? Don't worry, the marines and the Arbiter will lead you to it. Follow the narrow canyon like path and you'll find an open area with a nice little waterfall. Look left where the log is and jump over it.

After jumping, you'll hear a captain brute say, “Spread out you grunts, find them!" that’s because they also saw you crash here but Johnson found you first so too bad! Now kill the grunts first if you are playing on legendary or turned on the Catch skull because grunts just simply LOVE to throw plasma grenades and if you kill the brute leading them before killing them one of them will stick two or three plasma grenades on themselves and scream gibberish or "KAMIKAZE!!!" and charge towards you and with you trying to kill the more important enemies, you won't probably notice the insane grunt exploding in front of you and with the Iron skull activated, you simply won't like that. Then a Phantom will come and drop another squad of a brute and 5-6 grunts. Kill them. Simple as that! Then turn to your right and kill YET another squad... and get this, after you kill them, ANOTHER SQUAD comes right out of your next destination! Convenient or annoying? I'll let you decide. Then you'll get to a reintroduction of the Sleeping grunt, first introduced in Halo and removed in Halo 2, which the marines will advise you to take them out QUIETLY. How? By meleeing them, which counts as assassinations.
