Some of these logs are easy to find as part of linear main missions or sat in FOB bases, but the vast majority are spread far and wide across the game's world map and it can be rather tricky and time-consuming filling out your entire collection.
If you are planning on hunting most of the game's audio logs down on your own, remember to listen out for their distinctive proximity beeping sound which will help guide you in the right direction. Also remember that pulsing an area by pressing down on the d-pad is a big help here as it highlights the orange glowing aura of logs that are in your immediate vicinity.
With all that out of the way, let's get on with detailing the locations of all UNSC and Spartan audio logs in the game!
ALL UNSC AND SPARTAN AUDIO LOGS
UNSC The Prisoner Audio Logs
UNSC The Prisoner #01This log is right at the end of the Foundation level, you'll be asked to find a power seed to fire up an elevator to the surface. Head on as indicated in-game towards the seed's location and you'll also find this log sat next to it on the left.
UNSC The Prisoner #02
Our next log is in the Tower itself, as soon as you use the grav lift to enter the complex you'll face off against a few enemies then head up and around to the left, following the dark red corridors and facing off against charging foes. Keep searching around here and you'll find this one sat behind a pillar, as shown below.
UNSC The Prisoner #03
Next up we're in the Excavation Site as part of one of the main campaign missions and once you head up into the laser drilling machine in order to turn it off you'll find a few logs scattered around in close proximity.

SPARTAN AUDIO LOGS RETALIATION #03
This next one is straight across the river from our last in another great big hulking wreck.

Spartan Scattered Audio Logs
SPARTAN AUDIO LOGS SCATTERED #01Our next log is located in some grass just before a steep cliff edge that overlooks FOB Juliet. We've marked the exact location on our map below. It's also pretty easy to find if you position yourself with the FOB in the background as you can see it in our pic.
SPARTAN AUDIO LOGS SCATTERED #02
Just slightly west of FOB Juliet, you can find this Spartan log sat on a ledge just above an area that you may fought through to get your hands on a Spartan Core. Our map shows the exact location in which it's place but it's a good idea to pulse as you search, as it's well hidden.
SPARTAN AUDIO LOGS SCATTERED #03

SPARTAN AUDIO LOGS SCATTERED #08
This audio log is buried down in a cave network beneath the hill that we've marked in our map below. You'll need to get down here to grab a Spartan Core too so look out for that marker on your map and have a look around for the entrance which is a crack in the top of the cave that you can dive down into. Once in, take out the enemies and make your way around to the back, pulse with your radar if you're stuck, to find this one.
SPARTAN AUDIO LOGS SCATTERED #09
This next audio log is sat in the wreckage of a burnt out vehicle that's lying off to one side of the road into Ordo 'Mal's camp.
SPARTAN AUDIO LOGS SCATTERED #10
This next log is a tricky find but if you take a look at our map and pic below you should be able to pick it up. If you follow the road up north from FOB Juliet and then head right at the fork and look for a steep slope with the scorched marks of a huge vehicle crash running right up it with wreckage at the top, you're in the right location.
