Deposits earn Oil, Metal or Thorium resources at a set rate, continuously throughout the time you own it, without requiring a specific act of collection, like Oil Pumps and Metal Factories (While in your home base, if you look at your resource collection total, you will see the totals constantly increasing from the flow of resources from the deposits).
Each Deposit size contains set defenses that can be repositioned, but not be upgraded. In addition, you may add one Platoon of your own units (max 1500) to guard the deposit once in control of it.
Deposits can be obtained from either Rogue Factions (Yellow Color) or Enemy Players (Red Color). Control of Deposits is acquired by destroying all defense platforms from that deposit, and NOT the deposit building itself (the deposit building cannot be targeted).
Deposits on the map have a rising field around them, setting them apart from bases.
The resources aquired from Deposits DO NOT generate XP for the player.
You can increase the collection from your deposit by using this three tactical special ops, 18 Wheeler, Deuce and a Half & Dragonfly. Refer this article Special Ops .
