Completing Echoes of Victory Ridge in Arc Raiders is fairly simple, once you know where Victory Ridge is actually located. If you've been paying attention to your mission prompts, you might actually remember going to Victory Ridge for the Straight Record quest, where you disarm an EMP device.
Once you head to the right place, it's very similar to A Reveal in Ruins, i.e. a simple two step quest involving you finding a thing and bringing said thing back to the quest giver. If you want to make sure you get the item back in one piece, consider bringing a loadout with a safe pocket so you can immediately stow it in there.
