Looting is the name of the game in ARC Raiders. And while it's fun to loot every single container you come across, special drops and stashes will net you a lot more for a lot less trouble.
That's where Supply Drops come in, alongside other special-issue loot containers like Field Depots. As opposed to the latter, Supply Drops are much easier to obtain and can net you a good chunk of extra items and resources, as well as complete a quest for you.
