Spartan Ops/Season One/Didact's Hand/Random Transport/Walkthrough

Your load-out: BR, DMR, plasma grenades, auto sentry.
You will be dropped on top of a shack full of enemies. DO NOT ENGAGE! Instead, jump over the surrounded wall, turn right, and run like hell, until you reach the foot of the hill. You will need this spot later. Let's call this "Default fall back location"
From there, you can gradually move forward while snipping enemies. Watch out for snipers. Once you cleared the enemies, move back to the shack which you came from and you will see ammo racks (Let's call this "Ammo shack #1"). Rearm, you will see rocket launchers and SAWs, DO NOT TAKE THEM YET. At this point, let's get the landmarks clear: Facing the main building, on your left there is "Ammo shack #2," On your right there is "Ammo shack #3." On the other side of the building there is an open ammo rack (and a switch which you will need to activate). The entrance and up ramp of the main building is on your right. 
Now exit ammo shack #1 and walk towards ammo rack #2, you will notice its door is covered. As you approach the door will explode and enemies show up (with a single hunter). turn around and run, enter the main building and go up ramp, use the auto sentry to guard the ramp while you snipe from second floor. An elite might run up ramp so be careful. Snipe from second floor with your DMR. After the enemies are cleared, you will be notified to activate a switch (next to the open ammo rack). Run over there, activate the switch and immediately run back to 2nd floor, a drop pod will show up so start sniping (use the auto sentry as well). Before you drop the last grunt, jump of the building and switch your weapon to SAW and rocket at ammo shack #1 (this will be your weapon of choice for the rest of map). Go back to the building and finish the last grunt from second floor (conserve your ammo because the next wave will be big). Another switch will appear on top of the main building. Instead of going upstairs, go to the ramp and use auto sentry. Multiple drop pods will drop beaucoup enemies on ground and second level (including 2 sword elite on ground level). The enemies on second floor will not go to the ramp but those on ground level will. 2 sword elite will run up-ramp, finish them with rockets and if you miss, switch to SAW immediately! Once the sword elites are gone, the rest will be easier, stay in the ramp to finish off those on ground level (all stuck around entrance), once done go to ammo shack #1 to reload (it has unlimited ammo for SAW so you will need to come back often. Also get extra rockets at ammo shack #2). Once fully loaded go back to second floor to finish the rest (don't use the rockets yet). Once done jump back down to restock ammo. Once fully loaded go to the top floor to activate the switch. 2 Switches will appear at ammo shack #1 and #3, jump to the ground level and approach ammo shack #1, instead of activating it, run outside of the wall, turn right and run like hell to default fall back location. Drop pod will show up with multiple sword elites, grunts, jackals, the full house, right on top of ammo shack #1 (that's why DO NOT STAY). Let the sword elites come towards you and finish them with rockets and SAWS, gradually work your way back to ammo shack #1. Rearm, circle around to ammo shack #3 from outside the wall, again ammo shack #3 is covered, as you approached it will exploded and enemies will show up (with a single hunter). Use the SAW to thin out the herd, watch out for any charging sword elite (greet them with rockets and SAW). Go back to ammo shack #1 to rearm often. Finally take out the hunter with rockets. Go back to Ammo shack #1 to rearm before activate the switch.
Once the switch is activated, multiple drop pods will show up so run like hell back to default fall back location. These enemies will actively track you down so be careful. Ammo shack #2 is nearby so use the wall as cover (and take out the sniper). Use auto sentry as distraction while shoot from different direction. Once the enemy at ground level is clear, rearm and start shooting those at second floor. Once clear, move back to the building and work your way up and finally enter the portal.
